Answer:

C

Step-by-step explanation:

80/20 = 4 hours taken by Davie

90 mins = 1.5 hours

Horatio has 4-1.5 = 2.5 hours

Speed: 80/2.5 = 32 miles/hour

Answer:

C

Step-by-step explanation:

It will take Davie 4 hours to drive 80 miles at 20mph.

Horatio has to drive faster to reach the destination at the same time, if he drove 32 mph he will take 3hrs and 30 mins since Davie left 90 mins earlier.
