Question 1041572: a car is observed traveling between point a and point b in 3 seconds
it is known that the car is traveling at a steady speed of 25 mph
a second car is observed traveling between point a and point b in 1.5 seconds
what is the speed of the 2nd car?
what is the speed of the 3rd card observed to traverse the points in 2 seconds?

Since time is inversely proportional to speed:
3/1.5=n/25
1.5n=75
n=50 mph
The second car takes 1/2 the time, so it must be going twice as fast to cover the same distance.
For the third car:
3/2=n/25
2n=75
n=37.5 mph. ☺☺☺☺
