Question 786378: A car leaves town heading west at 57 km/h.
a) How far will the car travel in 7 hours?
b) A second car leaves town 2 hours after the first car, but it is traveling at 72 km/h. To the nearest hour, when will the second car pass the first? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Car A -- 57km/h - 7 hours
Distance = 399 km distance
Car A travels 57*2=114 km in 2 hours
it is 114 km ahead when Car B starts
Car B rate = 72 km/h
catch up speed = 72-57=15 km/h
distance = 114 to catch up
t=d/r
t=114/15
t= 7.6 hours to catch up
