You can put this solution on YOUR website! Two buses starts out from the same terminal and travel in opposite directions at the rates of 80 kph and 70 kph, respectively. In how many hours will they be 500 kilometers apart?
----------------
Going in opposite directions, their speeds are added --> 150 km/hr
----
d = r*t
t = d/r = 500/150
t = 3.333 hrs = 3 hr 20 mins
