Problema Solution
Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 75 miles per hour. The westbound train travels at 85 miles per hour. How long will it take for the two trains to be 192 miles apart?
Do not do any rounding.
Answer provided by our tutors
realtive velocity of the two trains = 75 + 85 = 160 miles per hour
time taken to be 192 miles apart = 192/160 hours = 1.2 hours = 1 hour 12 minutes
