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?.
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
