Let's denote s as the speed limit. To find the total time it takes for Jack to drive given the speed, we just divide the total number of miles he covered (10 miles) by the speed he's traveling at.
Accounting for the given of the problem, we'll have the following equation:

(from the fact that the difference between the time it takes to drive five miles below the speed limit versus 15 miles below is 2 mins or
