Vic is driving 450 miles to his grandma's house. if vic can drive 25 miles per gallon of gas, how many gallons if gas will he use round trip

In order to find the answer to this question, you need to multiply 450 by 2 to find the amount of miles in the round trip, which is 900.

Next, you divide 900 by 25, because that will leave you with the amount of gas it needs.

So the answer is 36.

P. S. I don't know if 450 miles is round trip or it is half. But if it is half, the answer would be 18
