Answer:
14mph
Step-by-step 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.
