Cyclists A and B each average 30 km/h for the first hour of a 100 km race.
At the end of the hour, B has a a mishap and loses 12 min.
Cyclist A finishes the remainder of the race at an average of 25 km/h.
If cyclist B averages 27.5 km/h after resuming, will B catch A before the finish line?
:
From the given information, I understand that both cyclist have 70 km to go.
Change 12 min to 12/60 = .2 hrs
:
Find A's time to finish the race
= 2.8 hrs
Add .2 hr to B's time to finish the race
.2 + = 2.745 hrs
Therefore
B will finish the race before A
