Question

11)A car can travel 300 miles on 20 gallons of

gas. Write an equation to represent the distance,y,
in miles James car can travel on x gallons of
gas? How many miles can it travel on 40 gallons of
gas?

Answer 1

y = 15x

600 miles

Explanation:

300/20 = 15

15 = miles per a gallon

Distance = 15x

y = 15x

We can create a ratio

300mi : 20g

Multiply by 2 on both sides

600mi : 40g

Hope this helps

Answer 2

y=15x

It can travel 600 miles on 40 gallons of gas.

Explanation:

300/20=15

y=15x

y=15(40)

y=600
