Question

A man drove 250 miles in 2.5 hours. If the posted speed limit was 75 mph the entire way how many miles per hour over the speed limit was he going?

A. 10 mph
B. 50 mph
C. 25 mph
D. 78 mph

Answer 1

C. 25 mph

Explanation:

First, find his speed in miles per hour:

250/2.5

= 100

This means he was going 100 mph

To find how much he was going over, subtract 75 from this

100 - 75

= 25

So, he was going 25 mph over the speed limit

The correct answer is C, 25 mph
