Question

If a bicycle tire has a radius of 18 inches, how many times will the tire rotate if the bicycle travels for half a mile?​

Answer 1

The tire will rotate 280.12 times

Why?

To calculate how many times will the tire rotate, first, we need to convert from miles to inches using the following factor:

`1mile=63360in\\\\0.5mile=31680in`

Now, calculating the circumference of the wheel, we have:

`C=2*\pi *r=2*\pi *18in=113.1in`

Then, calculating how many times will the tire rotate, we have:

`Revolutions=(31680in)/(113.1in)=280.12`

Hence, we have that the tire will rotate 280.12 times (280.12 revolutions).

Have a nice day!
