    has anyone verified that the speedometer is accurate, it may be showing 80, but the actual speed could be +/- 5 or 6.

    that would have a bearing on the distance travelled

    It doesn't matter if the speedometer is inaccurate, broken or if there isn't even one there in the first place. You are either travelling at 80mph or you are not. It takes an hour to travel 80 miles at 80mph

    Nothing is really that simple if you want to get ultra pedantic.
    She is travelling at 80mph in her car but the tectonic plate is moving at an inch a year and the planet is travelling at 66000 mph around the sun and also spinning on it's axis. We're also on the arm of a spiral galaxy that is also spinning and the universe itself is expanding at an increasing speed...

    I've driven at speeds up to and over 80 miles per hour (oh Montana!) on sparsely populated highways (oh Montana!). Going at a constant rate of speed, I still dealt with the car being pulled due to wind, the shifting of gears because of hills and mountains, and other variables that resulted in 80 MPH not equating to an hour of travel. Maybe an hour and a few minutes.

    Cars here at least, will be doing a little less than the indicated speed, so a few minutes extra will be taken than the indicated speed for an hour would suggest.

    Filming and talking to a camera he's holding while driving and SHE'S the dumb one? Yeah, go smoke another one bro.

    What if the sign on the outskirts of the town said 'Next Town 80 Miles' and he drove to the next town in an hour, but the distance was measured from the center of Main Street in each town, not the town limits?

    What if his watch stopped?

    They are both stupid if you ask me. Her for not getting what he is getting at and him for not taking into account any external factors.

    If I was asked that question, my first question in response would be are we talking 80mph by the speedometer in this car or the actual mathmatical equation. Because if you have a digital car speedometer, set it to 80mph an drive exactly 80 miles, will you cross the line on the hour mark? Not likely!

    No wonder the video ended when she asked to try it. He probably reset his distance gauge and started his stopwatch and couldnt fathom why it didnt turn to 80 miles when his watch turned to 60 mins!

    Not you.
    You're cool.
    But the rest of the nerds took it to extremes and ruined it!

    Haw haw haw stupid woman ... i am superior.

    whats that ... she runs a mile in 8 min's.

    I run/walk/whinge a mile in about 30 mins.

    I had factored that in with my initial calculation. Allowing for those variables, I came up with 1 hour to travel 80 miles at 80mph (give or take an hour or so :p)

    No that's not right - Half it!

    Speed is measured as distance over time. So if a car travels 80 miles in 1 hour, that is 80mph. Wind, snow or wheel diameters dont change that. They will only make the reading on the speedometer inaccurate.

    In any experiment, you need a someway controlled environment. If you have no way of verifying the speed, how can the 80 mph be maintained

    How anything is controlled or verified does not matter. 80 mph for 1 hour is 80 miles traveled in that hour. That fact an absolutely precise 80 mph cant be maintained or an exact time of 1 hour is not possible to measure in a car is a separate matter.

    That was staged, so therefore it's wasn't really funny...

    Wasted 2 minutes of my life watching that.

    But the video is over 4 minutes long. What did you do, just whack that in half?


  • Registered Users, Registered Users 2 Posts: 3,443 ✭✭✭Bipolar Joe

    You're not taking into account the variables! The rotation of the Earth at Aquarius34's latitude, the shifting tectonics, current time of day, kinesis, wind speed, maybe Aquarius34 shifted in their seat or moved the computer. YOU MUST ALLOW FOR ALL EVENTUALITIES!!!!

    this is clearly a setup and they are both taking the urine

    Most people I'm presuming have seen this video months ago because its been online for a long time. The funny thing about this thread though, is the people who think the guy is wrong for asking an unclear question... LOL

    The question is if I travel at 80mph for an hour... how far do I travel... or a variation of it

    The question isn't, how long will it take me to travel 80 miles, if I stop for a smoke, get stuck behind a truck in the overtaking lane etc etc.

    It's a perfectly reasonable question, simply solved by Dad's Silly Triangle; (Distance x Speed)/Time

    In fact the question he asks, is so simple, that anyone who even just comprehends the words he is speaking should be able to come up with an answer, the clue is in the 80 miles per hour

    /facepalm


  • Registered Users, Registered Users 2 Posts: 1,595 ✭✭✭Aquarius34


    You must have watched the video at a faster speed, i.e video second < actual second, so how long would it take to go 80 miles at 80mph of those time intervals ?

    Was she correct ? Was the guy correct ? Am I interested ? . . . sadly yes.

    No I stopped watching at 2 minutes. I could see it was fake, to all the posters who thought she was dumb, well they are dumb for thinking this was real.

    No one is "experimenting". The question is how long does it take......... etc. There was no qualification about location, temperature, wind resistance, planet revolution, time of the month, or colour of the bleedin' car. It is what it is, end of:rolleyes:

    Listen, if you are driving at 80mph constantly for eighty miles ot will take you an hour by definition. What's the problem?

    Relativity. The faster your go, the slower time passes. At just 80mph, the difference is negligible, but still there. Oh and then there's the earths rotation, it's orbit, our solar systems movement through the galaxy and it's movement through the universe. 1 hour isn't always 1 hour.

    If you are travelling at 88 MPH how long does it take to go 88 years into the future ?

    It just appears slower to the relatively stationary observer. For the traveler, its still an hour and still 80 miles.

    88 years + time dilation effects due to travelling at 88MPH (unless you're in a Delorean, and dependent on if the observer is doing the measuring).

    Whatever about the video, this thread has at least flushed out a bunch of After Hours "Einsteins".


  • Registered Users, Registered Users 2 Posts: 9,038 ✭✭✭Ficheall


    If you are actually travelling at a constant speed of 80mph, it will take you an hour to travel 80 miles.

    If you are not actually travelling at a constant speed of 80mph, then it won't necessarily take an hour to travel 80 miles.

    Perhaps it is the definition of "travelling" which some people ought to scrutinise?

    Not a bad looking goose.

    I think we are in agreement. When they make a footlong sub, they probably roll out the bread and cut it at the 12 inch mark. Some people may cut it just a centimeter or two short of a foot. Or, someone didn't let the bread rise long enough and the chain assumes that the bread reaches the 12 inch mark upon rising. Then again, maybe it's the oven that impacts whether a twelve inches of dough becomes or remains 12 inches of bread. The point is, you still buy a 12 inch sub because that is the standard measurement used by the chain, but there are variables that impact whether or not you got yourself 12 inches of goodness.

    Well, well, well:
