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
