two jets leave washington DC at the same time, one traveling north at 850km/h and the other traveling south at 750km/h. In how many hours will they be 4800 km appart.
Applying the distance formula of d=rt
Let t = time (hours) flying
then
850t + 750t = 4800
85t + 75t = 480
160t = 480
t = 480/160
t = 3 hours
