let time taken until they meet be t hrs
distance covered by first train = 115t miles
distance covered by 2nd train = 105t miles
115t+ 105t = 1200
220t = 1200
t = 5.454545.. hrs
or 5hrs and .4545..*60 min
= 5hrs and appr 27 minutes
(let's hope the trains are on different tracks)
a train leave Chicago at a 115 miles per hour towards Denver another train leaves Denver 105 miles per hour towards Chicago if the distance between the two cities is 1200 miles how long would it take before the two trains meet?
