Question

Write and solve an inequality.

The speed limit of a highway is 65 miles per hour. A car is traveling at least 74 miles per hour. How many miles per hour, m, over the speed limit is the car traveling?

Answer 1

• The car is travelling at least 9 mph over the speed limit

---------------------------

The speed limit is 65 mph, the speed of the car is at least 74 mph.

The difference m is the over the speed limit value.

Set an inequality:

• 65 + m ≥ 74
• m ≥ 74 - 65
• m ≥ 9
