Question

hello I was trying to do this question on my own for a while and haven't gotten the answer I need but hopefully you can help me and thank you for your time

Answer 1

given diameter (D) of wheel = 24 in rotation of wheel 455 rpm

circunference (C) = π⋅D

`\begin{gathered} C=\pi*24\text{ in } \\ C=\pi*(24)/(12)=\pi2\text{ ft/r} \end{gathered}`

455 rpm x 60 = 27300 r/h

27300 x 2π = 54600π ft/h

5280 ft = 1 mile

`(54600\pi)/(5280)=10.34\pi`

or 10.34 π mph
