At a speed of 50 miles per hour, a certain car uses 1 gallon of gasoline every 30 miles. If the car starts with a full 12 gallon tank of gasoline and travels for 5 hours at 50 miles per hour, the amount of gasoline used would be what fraction of a full tank?

a) 3/25
b) 11/36
c) 7/12
d) 2/3
e) 25/36

E) 25/36

Total miles - 50* 5 = 250 miles
total gallons used- 250/30 = 25/3

fraction of gasoline used - 25/(3*12) = 25/36
