Question

It usually takes Claude 40 minutes driving at 48 miles per hour to go from home to work. But due to road maintenance today, Claude has to take a detour, which makes the trip 8 miles longer than usual. What is the minimum speed Claude should travel so that he can reach the destination in less than 48 minutes?(1 point)

Answer 1

Answer:

50 miles per hour :)

Step-by-step explanation:

Distance = Speed * time = 48 * 40/60 = 32 miles

Detour is 8 miles longer so = 32 + 8 = 40 miles

In 48 minutes. Remember speed is in miles per hours.

Speed = Distance/ time

50MPH= 50 miles per hour

I hope that helps

Answer 2

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 hours.

Speed = Distance/ time

= 40 / (48/60)

= 50 miles per hour
