Question

Write a compound inequality that represents each situation. Graph your solution. On a road in the city of Rochester, the maximum speed is 50 miles per hour, and the minimum speed is 20 miles per hour.

Answer 1

Let s represent speed.

$20 \le s \le 50$

To graph it, draw a number line. Show zero, 20, 50 and arrowheads at both ends. Draw closed circles at 20 and 50 and shade in between.

Answer 2

Answer:

The compound inequality that represents this situation is:'

                      20 ≤ s ≤ 50

Step-by-step explanation:

We are given information that:

On a road in the city of Rochester, the maximum speed is 50 miles per hour, and the minimum speed is 20 miles per hour.

This means that the speed has to be greater than or equal to 20 but it can't exceed 50 i.e. it has to be less than or equal to 50.

Let s denote the speed.

This means that the compound inequality that can be formed using this information is:

                  20 ≤ s ≤ 50
