Question

Femi drives 18.4 miles in 16 minutes. He passes a sign which gives the speed limit as 55 mph. By how much, in mph, did Femi's average speed exceed the speed limit?

Answer 1

14mph

Explanation:

First, lets find how many 16s can go into 60.

We can find this by doing 60 / 16 = 3.75

Then we need to find his average speed. We can find this by doing

18.4 * 3.75 = 69

To find how much he exceeded the speed limit, we will subtract 55 from 69

69 - 55 = 14

Therefore, Femi's average speed exceeded the speed limit by 14mph.
