there is a road, that has a distance of 60 miles, with a wall at the very end, this road is very narrow. a car with a maximum speed of 60mph and half the speed when reverse managed to get to the end in 1 hour doing maximum speed, how long does it take him to get back to starting point?

on a very narrow road, would you do 30mph in reverse?
2007-04-12 03:46:30 · update #4
the count that is an excellent answer, but even if he drove 60mph on his return trip, do you honestly think he would do 30mph in reverse on the way? the external view is more complicated than the primary front.

I will offer my two cents worth and say that since the road is very narrow with a wall at the end, and you can go 30 mph in reverse, he would choose to drive to the wall in reverse, thus taking 2 hours to go, and at 60 mph in forward gear going back, the return trip would only take 1 hour.
that's my final answer ! lol !

He can't. Although his car was able to reverse at half of 60mph when he entered this road, I don't believe he could do it on the return trip.
If he transversed a 60 mile road in 1 hour with a car that could not travel over 60mph, it means he would've done a rolling, or flying start and a smashing finish.
The length of time for the return trip requires data specific to the tow truck used.
Or.... since you ask how long it would take him to get to the starting point? If you consider the front bumper as the starting point he may have reached it at the end of the road.

About an hour. Right? Who says the car needs to travel back to the starting point in reverse? Unless it is so narrow that it can't turn around at all. Then it should take a little over 2 hours, factoring in the time it takes to stop, put it in reverse, and work up to the speed of 30 mph. OK, tell me, how far off am I?

It'll be equivalent to the time it took you to get from start to finish. "You did say the road was narrow, but you didn't say there wasn't any room on the sides of the road to turn back on". Knowing that; I would say an hour as well (unless you meant with the time it took you to turn around alone with the acceleration).

if he is doing maximum speed, 2 hours

simple. it takes him 3 hours on the way back because he runs out of petrol and has to push the car all the way back.
