To get the amount of revolutions made, we are trying to compare the tyre circumference with the road distance, lets see how this works
The circumference of the circle is
[tex]\pi D=\pi\times26=81.68\text{ inches}[/tex]The distance ridden is
[tex]75\text{ f}eet=75\times12=900\text{ inches}[/tex]Whenever the car covers 81.68 inches, it does one revolution.
So if it takes 900 inches, it does
[tex]\frac{900}{81.86}=11.018\approx11\text{ revolutions}[/tex]Thus the tyre makes 11 revolutions while along this distance
