The end of a blade on an airplane propeller is 10 feet from the center. If the propeller spins at the rate of 1,980 revolutions per second, how many miles will the tip of the blade travel in one minute? (1 mile = 5,280 feet)	Choose the correct choice from the following answers: A) 200π B) 450π C) 300π D) 480π E) 1,200π
Distance traveled in 1 revolution = 2πr= 2π10/5280   Revolutions in one second= 1980   Revolutions in 60 seconds (one minute)= 1980*60   Total distance traveled= total revolutions *distance traveled in one revolution   1980*60 *2π10/5280= 450π   450π is the answer
