Question

A person leaves home at 8:00 a.m. and drives to a destination at a rate of 40 mph. The person returns at a rate of 25 mph and arrives at 2:30 p.m. If x represents how far it is to the destination, then which of the following expressions represents the amount of time to make the return trip?.

Answer 1

The time = X / 25

Hope this helps.

Answer 2

The best way to interpret this question is that the X is equals how far the destination is and the person rate in going home is 25mph. So the needed variable are X and the Speed. Speed has a unit of m/h and the distance is m so the answer should be x/25
