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
hours.)
Since we only have one unknown variable, we can freely solve for s:
(we ignore the negative value since there is no negative <u>speed</u>.)
ANSWER: The speed limit of the freeway is 65 mph.
B. If square-foot is on the x-axis then we can substitute for x in the equation and solve, and when we do, we get 2473.302 which is is B when rounded.
