<PRE><B>Question 1204171</B>

A bicycle has wheels 22 inches in diameter. A tachometer determines that the wheels are rotating at 120 RPM (revolutions per minute). Find the speed the bicycle is traveling down the road. (Round your answer to three decimal places.)

One rotation is equal to pi*d =pi*22 =69.08 inches
In one rotation the bike moves 69.1150 inches

In 120 revolutions it travels 120 *69.1150 =8293.804 inches=691.150 ft

691.50/60 = 11.525 ft/second (approx)

convert to mph
