Question

Ian​'s car can go 140 miles on 4 gallons of gas. During a drive last​ weekend, he used 5 gallons of gas. How far did he ​drive? Use pencil and paper. Explain how the problem changes if you were given the distance driven last weekend instead of how much gas he used.

Answer 1

The car would be able to drive 175 miles with 5 gallons of gas.

Explanation:

Every gallon of gas would give you 35 miles of distance.

To do this you divide 140 by 4 which is 35 that means 1 gallon of gas is 35 miles.

Add a extra gallon gas and also add the amount of distance the gas will give you (35 miles). Add that to 140 miles and then you get 175 miles.

For every 35 miles, I gallon of gas is used.

Hope this helps.

Answer 2

140 miles / 4 gallons = 35 miles per gallon.

35 x 5 = 175 miles
