A bicycle’s front wheel is traveling at 5 miles per hour. If the front wheel has a diameter of 25 inches, how fast is it turning in revolutions per minute? Use \(\pi ≈ 3.14\) and round your answer to the nearest whole number. (\(1\) mile \(= 63360\) inches)

relationship between mile and inches?
or just conversion relation between them. using D=pi*n*r. requires miles to be converted into inches.

Front-wheel speed \(= 5\) mph \(= 5 * 63360\) inches
Distance per minute \(= \frac{5 * 63360 }{60} = 5280\) inches
Wheel diameter \(= 25\) inches
circumference \(= πd = 25 * 3.14 = 78.5\) inches
No off revolutions \(= \frac{5280}{78.5} = 67.26 ≈ 67\) revolutions
Answer 67
