<h3><u>Time calculation</u></h3>
Given that June is driving from Brookline, Massachusetts to Brooklyn, New York, and the cities are 200 miles apart, and she can drive at a constant speed of 50mph the entire way, to determine the function that solves the time June takes to complete the route, the following calculation must be made:
- C / Constant speed = T
- 200 / 50 = T
- 4 = T
So it took June 4 hours to get from Brookline to Brooklyn.
