Question 358442: two cyclists are competing in a 12 miles race on a quarter mile circular track. They began at the same time. One biker's average speed is 24 miles per hour and the other's average speed is 30 miles per hour. How many complete laps will the slower cyclist have left to complete after the faster cyclist finishes? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! D=RT
12=30T
T=12/30
T=.4 HOURS TO COMPLETE THE 12 MILE RACE.
D=24*.4
D=9.6 MILES.
12-9.6=2.4 MILES LEFT AFTER .4 HOURS.
2.4/.25=9.6 LAPS REMAINING AFTER THE FASTER CYCLIST FINISHES.
