Two trains leave stations 456 miles apart at the same time and travel toward each other. One train travels at 85 miles per hour while the other travels at 105 miles per hour. How long will it take for the two trains to meet? Do not do any rounding.

train 1 = 85x  ( 85 miles per hour times x amount of time)

train 2 = 105x ( 105 miles per hour times x amount of time)

85x  + 105x = 456

190x = 456

x = 456/190 = 2.4 hours = 2 hours  and 24 minutes
