Question 171910
Two trucks left Buck's Trucks traveling in opposite directions. One truck traveled at a rate of 70 km/h, and the other at 80km/h. After how many hours were the trucks 900km apart?
-------------------------------------
The trucks are separating at the rate of (70+80) = 150 km/h
-------------------------
Time = distance/rate
Time = 900 km/150 km/h = 6 hrs.
