Answer:
The car that went 54 km in 2/3h was faster, 5/4 times faster than the other car
Explanation:
Average speed of a car is the ratio between the displacement
and the time (t) it takes to do that displacement:

So, for the first car:
(1)
for the second car we have:
(2)
So, the second cart is faster than the first one. To find how many times divide speed 2 by speed 1:
The magnitude of the ball's displacement when the ball is rolled uphill with a 5 meters before it slows, stops and begins to roll back and the ball rolls downhill 9 meters before coming to rest is 4 meter. Just subtract 9 meters with 5 meters. Therefore the answer is 4 meters.
