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

A.     9.5

B.     31.4

C.     53.4

D.     136.8

No. of miles per gallon = 22.5
No. of miles per liter = 22.5/3.8
No. of kilometers per liter = 22.5*1.6/3.8 = 9.5 (approx) ... B

I guess so..what's the answer?
