SAT Math Multiple Choice Question 127: Answer and Explanation
7. Officer Blake drives his squad car 1 mile per minute while patrolling local highways during his shift. If he has driven 480 miles by the end of his shift, how many total hours did he drive his car at the above rate?
- A. 8
- B. 12
- C. 16
- D. 20
Correct Answer: A
A Since Officer Blake drives 480 miles at a rate of 1 mile per minute, his total drive time was 480 minutes. The question asks for Officer Blake's driving time in hours, so you need to convert those minutes into hours. Since there are 60 minutes in 1 hour, you can divide 480 minutes by 60 to determine that Officer Blake drove for 8 hours, which is (A).
