Answer:
84 complete turns
Step-by-step explanation:
In order to find the number of turns that the bicycle wheel is going to take while going 792 feet, we need to find the circumference of the wheel.
![C = \pi \: d = 3.14 \times 3 = 9.42 \: ft \\ no \: of \: turns = \frac{792}{9.42} \\ = 84.0764331 \\ = 84 \: turns](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%5C%3A%20d%20%3D%203.14%20%5Ctimes%203%20%3D%209.42%20%5C%3A%20ft%20%5C%5C%20no%20%5C%3A%20of%20%5C%3A%20turns%20%3D%20%20%5Cfrac%7B792%7D%7B9.42%7D%20%20%5C%5C%20%20%3D%2084.0764331%20%5C%5C%20%20%3D%2084%20%5C%3A%20turns)
1/3 - 2/9 - 1/3
= -2/9
