Question 13 • 26-27 Ignite Technical Math-Financial Math - MA2007
Haley measured the distances between her house and two of her friends’ houses. Ellen’s house is 1.41 miles away from Haley’s, and Dirk’s house is 6,547 feet away from Haley’s. Whose house is farther away from Haley’s, and how many feet farther away is it, to the nearest whole foot?
Answer
A
Ellen’s house is 898 feet farther away than Dirk’s.
B
Ellen’s house is 1,659 feet farther away than Dirk’s.
C
Dirk’s house is 503 feet farther away than Ellen’s.
D
Dirk’s house is 1,267 feet farther away than Ellen’s.
Explanation
Convert Ellen’s distance to feet: 1.41 × 5,280 = 7,444.8 feet. Compare this with Dirk’s distance of 6,547 feet: 7,444.8 − 6,547 = 897.8 feet, which rounds to 898 feet. Ellen’s house is 898 feet farther away, matching choice a.
