<PRE><B>Question 821362</B>
A train leaves the station traveling north at 85 kilometers per hour. Another train leaves at the same time and travels south at 90 kilometers per hour. How long will it take before they are 525 kilometers apart?
--------
They are separating at 85+90 = 175 km/h
-----
Equation:
time = distance/rate
time = 525/175 = 3 hours
