What is the linear velocity in MILES PER HOUR of the tip of a lawnmower blade spinning at 2200 revolutions per minute in a lawnmower that cuts a path that is 26 inches wide?

Diameter=26"

So circumference = pi*diameter=81.8614 inches

2600rev/min=43.333 rev/sec

So in 1 rev = 1/43.333 sec

Speed = distance/time = 81.68 ÷ 1/43.333 = 3539.527 inches/sec = 294.96 ft/sec = 0.055863 miles/sec = 201.1mph.
