Question

The Ortiz family will travel from Indianapolis to Denver this summer. The driving distance between the two cities is 1,058 miles. They need to find out about how much the gas will cost round trip. Their car gets about 20 miles per gallon. A. Write and solve an algrebraic equation to find out how many gallons of gas they will use. Explain your steps. B. Write and solve an algebraic equation to find out how many miles they will travel.

Answer 1

A. Write and solve an algrebraic equation to find out how many gallons of gas they will use. Explain your steps.

let x = gallons of gas they will use
    y = distance traveled

x = y/20 
x = 1058/20 = 52.9 gallons of gas

B. Write and solve an algebraic equation to find out how many miles they will travel.

let x = distance traveled
    y = gallons of gas used

x = 20y
x = 20(52.9) 
x = 1058 miles

Hope this helps. Have a nice day.
