Question

Carmen is taking a road trip. After 25 miles, she reaches a stretch of highway where she can drive at a constant speed of 65 miles per hour. Carmen's friend in the passenger seat is trying to figure out the minimum number of hours Carmen will need to drive to reach over 350 total miles for the trip, assuming she keeps a steady pace. Carmen's friend creates the inequality 65t + 25 > 350, where t is the driving time, in hours. What statement is the most accurate?

Answer 1

Answer: t > 5

Explanation:

350 - 25 = 325

325 / 65 = 5

It said to reach over 350 miles, so it’s greater than 5

t > 5

Answer 2

Carmen needs more than 5 hours to meet her goal.

Explanation:

65t + 25 > 350

65t > 325

t > 25

Carmen could reach 350 total miles at 5 hours if she drives at a constant rate of 65 miles per hour. To reach over 350 miles, Carmen will need to drive for more than 5 hours.

So, Carmen needs more than 5 hours to meet her goal.
