At 9AM, a freight train leaves Boston for NYC, traveling at an average rate of 24 miles per hour. At noon, a passenger train sets out on the same route, traveling at an average rate of 60 miles per hour. How far from Boston do the two trains pass each other? ============= At noon, the freight train is 72 miles away (24*3). --- The Pass train "gains on" it at 36 mi/hr (60 - 24). They meet at 72/36 = 2 hours. ============== Distance from BOS = 2*60 = 5*24 = 120 miles
