Hello Guest!

 

\(n=\dfrac{s}{d\cdot \pi}\)

mi = in * 0.000015783

\(n_{car}=\dfrac{10\cdot 10^3mi}{17in\cdot \pi}\cdot \dfrac{in}{0.000015783mi} \)

\(n_{car}=11863467.6\ revolutions \)

 

\(n_{bike}=\dfrac{10\cdot 10^3mi}{26in\cdot \pi}\cdot \dfrac{in}{0.000015783mi} \)

\(n_{bike}=239254.9\ revolutions \)

 

\(n_{sb}=\dfrac{10\cdot 10^3mi}{19.5in\cdot \pi}\cdot \dfrac{in}{0.000015783mi} \)

\(n_{sb}=10342510.2\ revolutions \)

Why didn't you just ask for one of these and then copy the method to do the other 2 yourself?

 

Is it because you are only really interested in the answers?
