Answer should be $174.91? if that isnt an option tell me and i will regroup
Circumference = PI x Diameter
circumference of tire = 3.14 x 1.1 = 3.454 feet
so every full turn of the tire the bike travels 3.454 feet
110 feet / 3.454 = 31.8 turns
5 3/5 as an improper fraction is 28/5.
I hope this is helpful! :D
I hope this helps you

Answer:
The final velocity v is 21.74 m/s.
Step-by-step explanation:
Given:
![\textrm{initial velocity} = u = 9\ m/s\\\textrm{acceleration} = a = 7\ m/s^{2}\\\textrm{distance} = s = 28\ m](https://tex.z-dn.net/?f=%5Ctextrm%7Binitial%20velocity%7D%20%3D%20u%20%3D%209%5C%20m%2Fs%5C%5C%5Ctextrm%7Bacceleration%7D%20%3D%20a%20%3D%207%5C%20m%2Fs%5E%7B2%7D%5C%5C%5Ctextrm%7Bdistance%7D%20%3D%20s%20%3D%2028%5C%20m)
To find:
![\textrm{final velocity} = v = ?](https://tex.z-dn.net/?f=%5Ctextrm%7Bfinal%20velocity%7D%20%3D%20v%20%3D%20%3F)
Solution:
As we know the third equation of motion is represented as
![v^{2} = u^{2} + 2\times a\times s\\](https://tex.z-dn.net/?f=v%5E%7B2%7D%20%3D%20u%5E%7B2%7D%20%2B%202%5Ctimes%20a%5Ctimes%20s%5C%5C)
Substituting the values u, a and s in the above equation we get
![v^{2} = 9^{2} + 2\times 7\times 28\\ =81 + 392\\=473\\](https://tex.z-dn.net/?f=v%5E%7B2%7D%20%3D%209%5E%7B2%7D%20%2B%202%5Ctimes%207%5Ctimes%2028%5C%5C%20%3D81%20%2B%20392%5C%5C%3D473%5C%5C)
![v =\±\sqrt{473} \\v =\sqrt{473} \ \textrm{as acceleration is positive v is also positive}\\v = 21.74\ m/s](https://tex.z-dn.net/?f=v%20%3D%5C%C2%B1%5Csqrt%7B473%7D%20%5C%5Cv%20%3D%5Csqrt%7B473%7D%20%5C%20%5Ctextrm%7Bas%20acceleration%20is%20positive%20v%20is%20also%20positive%7D%5C%5Cv%20%3D%2021.74%5C%20m%2Fs)
