You can put this solution on YOUR website! A train leaves Arkansas, and travels north at 80 kilometers per hour. Another train leaves at the same time and travels south at 55 kilometers per hour. How long will it take before they are 270 kilometers apart?
--------
They are separating at a rate of (50+55) = 105 km/hr
-----------------
Equation:
time = distance/rate
time = 270 km/(105 km/hr) = 2.57 hours = 2 hr 34 minutes
