A train traveling 50 mph left a station 30 minutes before a second train running at 55 mph. How soon did the second train overtake the firstIf 50x represents the distance the slower train travels, then the faster train travels?

Train A : 50 mph
Train B : 55 mph

After 30 mins train A has travelled 25 miles
Relative speed of trains is 5 mph

Consider train A at rest and train B at 5 mph

t = 25 / 5 h

t = 5 h

Second train overtakes after 5 h
