You can put this solution on YOUR website! Yesterday, two cars started from two stations 240 km apart and they traveled toward the direction of their route. One traveled at 75 kph and the other at 85 kph. If they started at the same time,how long would it take them to meet?
----
Assuming they were driving toward each other,
their closing speed was 75 + 85 = 160 kph
-----
time = distance/rate
time = 240/160
time = 1.5 hours
