Q37:

If an automobile averaged 22.5 miles per gallon of gasoline, approximately how many kilometers per liter of gasoline did the automobile average?  (1 mile = 1.6 kilometers and 1 gallon = 3.8 liters, both rounded to the nearest tenth.)

A.       3.7

B.       9.5

C.       31.4

D.       53.4

E.        136.8

我选D 答案是B

22.5*3.8/1.6=53.4哪里错了呢？谢谢指点。

可口不可乐

应该是22.5*1.6/3.8=9.5

22.5miles=22.5*1.6kilometers
