The first train leaves a station at a speed of 72 mph. The second train leaves the same station 1 hour later and follows the sam
e route at a faster rate of 90 mph. In how many hours will the second train catch up with the first?
1 answer:
Equation:

72x = 90(x-1)
72x = 90x-90
18x = 90
x = 5 hrs
x-1 = 4 hrs
