Question

Willow is driving on the freeway. She just passed mile marker 325 . The markers have been increasing as she drives by them. The fastest Willow will drive is 75 miles per hour. However, there is a bit of traffic that might slow her down, but she doesn't know exactly how much it will slow her down. Rewrite and select the inequality revealing Willow's speed.

A. r≥150
B. r≤75
C. r≥75
D. r≥80

Answer 1

The correct inequality for Willow's speed on the freeway, where the maximum speed is 75 miles per hour, is 'r≤75', implying that her speed will not exceed 75 mph. Therefore, the correct answer is option B. r≤75.

Step-by-step explanation:

The inequality revealing Willow's speed as she drives on the freeway after passing mile marker 325, where the mile markers have been increasing, and her maximum speed is 75 miles per hour, would be r≤75. This is because the fastest she will drive is 75 miles per hour, and traffic may slow her down but cannot make her go faster than 75 miles per hour. Therefore the correct inequality is B. r≤75, indicating that her speed r is less than or equal to 75 miles per hour.
