How far is 100 yards on the treadmill?

This is not very hard to figure out.

Hopefully you know there is 5280 feet in a mile, and three feet in a yard.

So, all you have to do is times 3*100=300.

Than, you divide 5280 by three hundred, and you get 17.6 of a mile, so you can round that up to .18 of a mile.

Shortly, it is equal to 17.6 of a mile.
