Answer:

Option D

Explanation:

Given that John drives 257 miles and uses 9 gallons of gas.

we can find unit rate as

Per galon mileage given = 257/9 = 28

ANd units are miles/gallon

100 miles per gallon is very far from 28 hence incorrect

6 miles per gallon is very low

30 is right but unit is wrong

Hence option D is the right answer.
