Afreight train leaves a station traveling 60 miles per hour. thirty minutes later a passenger train leaves the station in the same direction on a parallel track at the speed of 72 miles per hour. how long will it take the passenger train to catch the freight train?

The passenger train will take 2.5 hours to catch the freight train.
