Question

A car can travel 476 miles on 14 gallons of gas.Write an equation relating the distance d to the number of gallons g.How many gallons of gas does this car need to travel 578 miles?

Answer 1

mpg = (d)istance traveled divided by (g)as used

mpg= 476/14
mpg=34

34 = d/g
34 = 578/g
g = 578/34
g = 17 gallons

You need 17 gallons to drive 578 miles.
