Question

two trains leave the station at the same time one heading east one heading west. the eastbound train travels at 85 miles per hour. the westbound train travels at 105 miles per hour. How long will it take for the two trains to be 456 miles apart

Answer 1

Train1 = 85 mph

Train 2 = 105mph

85+105 = 190 mph combined speed

Time = distance/ speed

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