Question

Savannah and Sarah are planning on riding their bikes to a point located 1100 feet from their house. Their bicycles have a diameter of 26 inches. How many revolutions will their tires make on the path from their house to the park?

Answer 1

161.4 revolutions

Explanation:

Answer 2

162 revs

Explanation:

-The distance to be covered is 1100 ft.

-The circumference of the tire is equivalent to the distance covered by the tire in one revolution.

#We find the tire's circumference in feet(1inch=0.08333)

`C=\pi D\\\\=\pi* 26\\\\=26\pi \\\\=81.6814 \inch * 0.08333\approx 6.8065\ ft`

We then divide the distance to be traveled by the tire's circumference to determine the number of revolutions made:

`revs=(d)/(C)\\\\=(1100)/(6.8065)\\\\=161.6102\approx 162 \ revs`

Hence, the tire makes approximately 162 revs.
