Question

What is the total width of the path in feet

Answer 1

Between the 3 and five minutes, the turtle travels 1 foot. This means that it took the turtle 2 minutes to travel 1 foot. 
The rate of the turtle is 1/2ft per minute.

Using the first bit of information:
3 minutes= 1.5 feet+2.5

The length of the path is 4 ft.
