Tour buses A and B both cover the same route. Tour Bus B takes 20 minutes longer than tour bus A to complete the route. How long does it take for Tour Bus A to complete the route if it travels at 60 mph and Tour Bus B at 50 mph?

Let the distance covered be x miles
x /50 - x/60 = 1/3
MULTIPLY BY 300
6x - 5x = 100
x = 100 miles
A = 100/60 = 1 hour 40 minutes ANSWER
B = 100/50 = 2 hours ANSWER
x /50 - x/60 = 1/3
MULTIPLY BY 300
6x - 5x = 100
x = 100 miles
