liang has a goal of walking at least 18 miles she walks at a rate of 4 miles per hour. what inequality can liang use to find h number of hours she should walk in order to meet or exceed her goal

4h >= 18

To find the inequality that Liang can use to determine the number of hours she should walk in order to meet or exceed her goal, we can use the formula:

Distance = Rate × Time

In this case, Liang's goal is to walk at least 18 miles, and she walks at a rate of 4 miles per hour. Let's denote the number of hours she should walk as 'h'.

Based on the formula above, we can write the inequality as follows:

Distance ≥ Goal

Rate × Time ≥ Goal

4 × h ≥ 18

The inequality that Liang can use to find the number of hours she should walk in order to meet or exceed her goal is:

4h ≥ 18
