To solve the problem, we need to multiply the average miles per gallon by the number of gallons of gas.

23 2/5 x 19 3/7 can be rewritten as (23 + 2/5) x (19 + 3/7)

= 23 x 19 + 23 x 3/7 + 2/5 x 19 + 2/5 x 3/7

= 437 + 69/7 + 38/5 + 6/35

= 454 22/35

Therefore, the car will travel 454 22/35 miles on 19 3/7 gallons of gas. The best choice is (D).
