Answer:

756

Step-by-step explanation:

If you recognize that 12 (=8 +8/2) is half-again as much as 8, then you would know that Tom would drive half-again as much as 504 miles. That is, he would drive 504 +504/2 = 504+252 = 756 miles in 12 hours.

Since the rate is constant, you can write a proportion:

d/12 = 504/8 = distance/time

d = (12/8)(504) 1.5×504 = 756

Tom would drive 756 miles in 12 hours at that rate.
