Two buses start out from the same terminal and travel in opposite directionat the rates of 80 kph and 70 kph, respectively. In how many hours will they be 500 kilometers apart?
Answer provided by our tutors
The time they are 500 kilometers apart is x
So the equation is
500 = 80x + 70x
So
x = 10/3
So the time they are 500 kilometers apart is 10/3 hours
