Answer 1

171 / 7.6 = 22.5 miles per gallon

22.5 x 12.5 = 281.25 miles she can drive

Answer 2

She can drive 281.25 miles in 12.5 gallons.

Explanation:

Consider the provided information.

Sara drives 171 miles on 7.6 gallons of gas.

Thus in 1 gallons of gas she can drives:

`171\ miles = 7.6\ gallons`

`(171)/(7.6)\ miles =1\ gallon`

`22.5\ miles =1\ gallon`

She can travel 22.5 miles in one gallon or she can drive 22.5 miles per gallon.

To find how many miles she can drive on 12.5 gallons of gas, simply multiply the number 22.5 with 12.5.

22.5×12.5=281.25

Hence, she can drive 281.25 miles in 12.5 gallons.
