Two trains, traveling towards each other, left from two stations that are 900 miles apart, at 4 pm. If the rate of the first train is 72 mph and the rate of the second train is 78 mph, at wthat time will they pass each other?

• distance to be covered =900 miles
  time to pass each other =900/(72+78) hr= 6hr
  thus 4 pm+6 hr=10 pm .hence car pass each other at 10 pm
