Question

Zach's car travels 21 miles on 1 gallon of gas. Write an equation to represent the relationship between the gas Zach's car uses and the distance he travels. Then solve the equation to see how far Zach's travels on a trip if he uses 16 gallons of gas

Answer 1

Zach's car can travel 336 miles on 16 gallons of gas

Explanation:

21 miles per 1 gallon is a ratio of 21:1 or a fraction of . You can now set up a ratio/fraction to see how many miles 16 gallons is. If 1 gallon of gas can take a car 21 miles, then set up a fraction . Cross multiply. 21 x 16 = 336. 336 divided by 1 equals 336 so the answer is Zach's car can travel 336 miles on 16 gallons of gas.

Answer 2

Zach's car can travel 336 miles on 16 gallons of gas

Explanation:

21 miles per 1 gallon is a ratio of 21:1 or a fraction of
`(21)/(1)`. You can now set up a ratio/fraction to see how many miles 16 gallons is. If 1 gallon of gas can take a car 21 miles, then set up a fraction
`(21)/(1) (x)/(16)`. Cross multiply. 21 x 16 = 336. 336 divided by 1 equals 336 so the answer is Zach's car can travel 336 miles on 16 gallons of gas.
