Problema Solution
Two buses start out from the same terminal and travel in opposite direction at the rates of 80 kph and 70 kph, respectively. In how many hours will they be 500 kilometers apart?
Answer provided by our tutors
Thus they move in different directions:
Thus the speed becomes 80+70=150kph
distance=500km
time in hrs=500/150
=10/3=3.3 hrs
