Question

A tire measures 20 inches in diameter. How many revolutions will the tire have completed when it has traveled 100 yards? Express your answer to the nearest whole number.

Answer 1

Number of revolutions required to travel 100 yards is 57.

Step-by-step explanation:

Diameter of tire,D = 20 inches

Perimeter of tire = πD

Perimeter of tire = π x 20 = 62.8 inches

Distance traveled = 100 yards

1 yard = 36 inches

Distance traveled = 100 x 36 = 3600 inches

In one revolution it travels 62.8 inches.

`\texttt{No of revolutions = }(3600)/(62.8)\\\\\texttt{No of revolutions = }57.32\\\\\texttt{No of revolutions = }57`

Number of revolutions required to travel 100 yards is 57.
