Question 412915: A train leaves Little Rock,Arkansas, and travels north at 85 kilometers per hour. Another train leaves at the same time and travels south at 60 kilometers per hour. How long will it take before they are 435 kilometers apart? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! train A speed = 85 km/h--- north
Train B speed = 60 km/h --- south
..
opposite directions
so add speeds
85+60=145 km/h
..
distance = 435 km
Time = d/s
435/145
= 3 hours
