Arithmetic Reasoning
Yesterday I presented a question about miles per gallon. Jack buys gas for $3.50 a gallon. His car gets 20 mpg. How much will a trip of 600 miles cost? Do you know how to solve this problem?
As an ASVAB tutor, I see the great importance of reviewing miles per gallon questions with the students in my ASVAB prep course. This question is not solved as a proportion.
Gas costs $3.50 per gallon.
The car gets 20 mpg.
The trip is 600 miles.
There are 3 values in this problem. Two of them are numbers, and one is a money amount.
Divide the number into the number.
Then multiply by the money.
600 divided by 20 = 30
Then multiply $3.50 by 30 = $105.00
The cost would be $105.00
Did you solve this problem correctly?
