QWD3-Q14

Q14: 

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)

A.      8

B.       9

C.      10

D.      11

E.       12

答案是c，貌似我老算不对，原谅我的笨吧，请nn指教

1 mile=1,760 yards

45 m/h=45*1760/3600 y/s=22 y/s

so the question should be to travel a distance of 220 yards
