tt gwd-3-14 奇怪,求助!!

14. how many seconds will it take for a car that is traveling at a constant rate of 45 miles per hour to travel a distance of 22 yards? ( 1 mile = 1,160 yards)

i did this question in this way: - 45 miles*1160 = 52200 yards / 3600 sec.= 14.5 yard/ sec

- 22 / 14.5 = 1.5 sec.

why the answer is 10 seconds.

anybody help me?
