标题: 请教GWD3的一道数学题14

Q14:

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

A. 8

B. 9

C. 10

D. 11

E. 12

Answer:C

我算不出任何一个答案：

我是这样算的，不知道哪里错了。谢谢！

Distance=22 (yard)

Speed= 45 (miles/hour)=45*1160/3600 (yard/second)

Time = 22*3600/(45*1160) = 1.51 second
