.
Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 80 mph. The westbound train travels at 60 mph. How long will take for the two trains to be 196 miles apart?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The rate increasing the distance between the trains is 80 + 60 = 140 mph.
Therefore the time under the question is
Time = = = = hour = hour = 1 hour 24 minutes.
