The wheels on a vehicle have a radius of 17 inches and are turning at 700 revolutions per minute.
What is the linear velocity of the wheels in miles per hour?
a. 52.2 mi/hr
b. 51.4 mi/hr
c. 51.8 mi/hr
d. 53.5 mi/hr
Inches per hour = 700 * 2 * pi (17) * 60 ≈ 4486194 in / hr (1)
Inches in one mile = 5280 * 12 = 63360 (2)
Mph = (1) / (2) = 4486194 / 63360 ≈ 70.8 Mph
