Question 1048935: A bike is traveling at 10 mph. Determine number of revolutions the wheels make in 1 min.
Circumference of wheels: 28 in.
Solution provided with problem:
Let n = number of revolutions.
In 1 min. the wheels travel pi * 28 * n inches.
In 1 hr. the wheels travel pi * 28 * n * 60 inches.
= pi * 28 * n * 60 in. / 5280 * 12 miles. **
= pi * 28 * n * 60 in. / 5280 * 12 = 10 **

= pi * 7 * n / 88 * 3 = 10 **
n = 10 * 88 * 3 / pi * 7 **
= 10 * 88 / 7 = 125.74
n = 120
