A train leaves Los Angeles at 2 p.m. heading north at 50 mph. If the next train leaves three hours later and also heads north at 60 mph, at what time will the second train catch up with the first?
First train has a 50 m/hr x 3 hr = 150 mile head start
Second train is going 60 - 50 = 10 m/hr faster and will close this 150 mile distance
in 15 hours to catch the first train
2pm + 3 hours + 15 hours = 8 am
