Answer: 50 miles per hour
Step-by-step explanation:
Find out the length of the normal route.
Distance = Speed * time
= 48 * 40/60
= 32 miles
The detour is 8 miles longer so the length is;
= 32 + 8
= 40 miles
What speed should he travel at to make it in 48 minutes. Remember speed is in miles per <u>hours</u>.
Speed = Distance/ time
= 40 / (48/60)
= 50 miles per hour
