Question

Erin and her friends are taking a road trip. She has agreed to drive between hours 3 and 6 of the trip. If h represents the hours of the trip Erin will be driving, then h ≥ 3 and h≤ 6 represents her portion of the driving. While she is driving, her distance and time are modeled by the inequality d < 70h. What are the possible hours and distances Erin could be driving?

Answer 1

Erin could be driving for any amount of time between 3 and 6 hours, and her distance could range from 210 to 420 units.

Step-by-step explanation:

Based on the given information, the possible hours Erin could be driving are between 3 and 6. This can be represented as 3 ≤ h ≤ 6.

The distance d that Erin drives is modeled by the inequality d < 70h. In order to find the possible distances, we substitute the values of h between 3 and 6 into the inequality.

For h = 3: d < 70(3) = 210.

For h = 4: d < 70(4) = 280.

For h = 5: d < 70(5) = 350.

For h = 6: d < 70(6) = 420.

The possible distances Erin could be driving range from 210 to 420.
