Answer:
11 hours
Explanation:
To solve this problem, we need to find how long it takes him to drive 1 mile at that rate.
504 miles, 8 hours is the information we have, and they are asking us how long it would take him to drive 693 miles.
So, if we divide 8 by 504, we can determine how much time it would take him to drive one mile.
8/504 = 0.0159 hrs per Mile
Because we know the unit time for one mile, we can multiply it by 693, the target distance to derive our answer.

Your answer is 11 hours.
