The point will move the distance equivalent to the circumfrance of a circle with a diameter of 29.10 inches
circumfrance of a circle is Pi*diamerter
3.14 * 29.1 = 91.374in
for the bonus divide a mile by 91.374in to get the number of revolutions.
A Michelin Cross Terrain SUV tire has an overall diameter of 29.10 inches. How far will a point on the tire tread move in one complete turn?
Bonus question: How many revolutions does the tire make per mile? Round to the nearest whole number.
Again, this is an odd problem in my book, so I know the answer is 91.4 in and the bonus answer is 693 revolutions/mile (rounded) but I cannot figure out how they came up with this solution.
