Davie and Horatio are riding their motorbikes on a scenic tour that is 80 miles long. Davie rides at 20 miles per hour and leaves 90 minutes before Horatio. How fast must Horatio ride to finish at the same time as Davie?
A 24 mph
B 24.5 mph
C 32 mph
D 33.3 mph

Respuesta :

C 32, Dave will take 80/20 = 4 hours to finish.  Horatio only has 2 and a half hours to cover the same distance (80 miles).  80/2.5 = 32

C 32, Dave will take 80/20 = 4 hours to finish
