Question 621651
Two cars leave the same place at the same time, one going east and one going west. The eastbound car averages 40mph, while the westbound car averages 50mph. In how many hours will they be 300 miles apart
.
Let x = time (hours) traveled
then applying the distance formula (d=rt):
40x + 50x = 300
90x = 300
x = 300/90
x = 3.33 hours
or
x = 3 hours and 20 minutes
