To find out how many gallons of gas Chris would need to drive 275 miles at the same rate, we can set up a proportion:

( \frac{250 \text{ miles}}{9 \text{ gallons}} = \frac{275 \text{ miles}}{x \text{ gallons}} )

Solving this proportion:

( 250 \times x = 9 \times 275 )

( 250x = 2475 )

( x = \frac{2475}{250} )

( x = 9.9 )

So, Chris would need approximately 9.9 gallons of gas to drive 275 miles at the same rate.
