two cars are running at 100 mph ,one runs faster,how come?

Answer 1

There is a number of impossibilities that I could rattle on about that question from a scientific point, but I will play along with the question -

One car is driving uphill, the other car is driving downhill, or of course the road difference effect distance travelled, the type of surface the 2 cars is different meaning faster movement for one than the other.

Of course 1 of the cars could have the hand brake on.

Answer 2

I would guess that one or both of them is not in fact running at 100mph (or the velocities are being measured relative to different reference points)

measurement error is common with speedometers so two cars that both show 100 mph on their speedometers might be going quite different speeds

small things like tire inflation or tire size can have a significant affect on the speedometer reading

i maintain that if two cars are actually going 100 mph relative to the same reference point, then neither car runs faster, relative to that reference point

one might appear faster for a number of reasons

Answer 3

Theoretically they are running at the same speed. In actual, the other one could be running faster even though at the same 100 mph from the speedometer reading, because of some reason: 1. assuming they both have the same tire size, the faster car has proper tire pressure while the slower has softer tires. 2. Speedometers not calibrated properly.

Answer 4

If you are talking about in a 1/4 mile, from a standstill, it's simply because one accelerates to 100mph faster than the other. If they are both traveling over the same distance, at the same speed, neither will be faster. It doesn't matter if they are going up or down a hill if they are going the same speed. That would only be relevant if they were speeding up or slowing down. Also, if it is the same distance, a curvy road would not matter.

Answer 5

They are both running at exactly the same speed, one may pull ahead of the other though as it may be covering less distance.

Take an american style race track.

If 2 cars cover the race distance going at the same speed and one runs at the top of the track, and the other at the bottom, the one at the bottom will win, and have faster lap times, because it travels less distance during the race.

Answer 6

100 mph =100 mph = 100 mph

Answer 7

Your question doesn't really make sense. If you mean one gets to the destination faster, maybe they take paths of different lengths. If you mean one engine is spinning faster, that depends on the gear ratio of the transmission and the size of the tires.

Answer 8

Their speedometers are out of sync for some reason. Outsized or undersized tires on either car would do it.

Answer 9

One car is probably a little lighter, or the speedometer is messed up.
