Question

Robert's car used 5 gallons

of gas to drive 100 miles.
How many miles can he
drive with 16 gallons of gas?

Answer 1

320 miles

Explanation:

5=100 SO 1=20

you need 16 gallons

So - 16 x 20= 320

Answer 2

320 miles

Explanation:

Use a proportion.

5 gallons is to 100 miles as 16 gallons is to x miles.

5/100 = 16/x

1/20 = 16/x

x = 20 * 16

x = 320

Answer: 320 miles
