Question

John is driving the country. He used 75 gallons of gas in 5 days. If he keeps using the gas at the same rate, how many gallons will he use in 8 days?

Answer with supporting work:

Answer 1

120.

To find out how much gas he is using per day, you can use 75/5 which comes to 15. Then multiplying 15 with the 8 days, you get a sum of 120.
