PSAT Math Multiple-Choice Question 271: Answer and Explanation

Question: 271

Veronica gets stuck at an intersection with road construction on her way to work and is running late. She has 25 minutes to travel 40 miles. How fast would she need to drive if she wanted to get to work on time?

• A. 85 mph
• B. 100 mph
• C. 96 mph
• D. 90 mph

Correct Answer: C

Explanation:

Veronica would need to drive 96 miles per hour to make it to work in 25 minutes because she has 40 miles to go and (40 miles ÷ 25 minutes) x 60 minutes in an hour = 96 mph. See Lesson: Solving Real-World Mathematical Problems.
