Hi Guys,
I came across the following question when I was doing a practice GMAT today:
A certain car averages 25 miles per gallon when driven in the city and 40 miles per gallon when driven on the highway. According to these rates, which of the following is closest to the number of miles per gallon that the car averages when drive 10 miles in the city and then 50 miles on the highway?
A. 28
B. 30
C. 33
D. 36
E. 38
I have tried numerous ways to work out this solution but I keep getting an answer that isn't listed (37.5). And rounding 37.5 to the nearest mile, 38, gives you the wrong solution. The correct answer is D 36.
Please help.
Thanks.
