Question

A bus travels 150 Miles on 15 gallons of gas. How many gallons will it need to travel 220

Answer 1

Answer:

22

Step-by-step explanation:

220 x 15 ÷ 150 = 22

or each gallon gives him 10 miles.

for 220 miles he needs 22 gallons

Answer 2

Answer:

22 gallons

Step-by-step explanation:

You need to do proportions. This expression means miles per gallon:

$\frac{miles}{gallons}$

The equation will look like:

$\frac{150}{15} =\frac{220}{x}$

Then, you cross multiply.

150x = (220)(15)

150x = 3300

Then, divide.

$\frac{3300}{150} = 22$
