Question: 581

17. At a track meet, Brian jumped a distance of 14 feet, 9 inches. If Mike jumped exactly 2 feet farther than Brian, how far did Mike jump?

(1 foot = 12 inches.)

A. 17 feet, 6 inches
B. 17 feet, 5 inches
C. 17 feet, 3 inches
D. 17 feet, 2 inches
E. 17 feet, 1 inch

Correct Answer: C

Explanation:

C We need to have all the quantities in the same form of measure, so convert both into inches. Brian jumped 14 ft., 9 in., which is (12 × 14) + 9 = 177. Mike jumped 2 feet further, which is 30 inches further: 177 + 30 = 207. Look at the answers—all of them mention the distance of 17 feet: 17 × 12 = 204 inches, which is 3 inches less than the total of 207. Mike therefore jumped 17 feet, 3 inches, as in C.
