The end of a blade on an airplane propeller is 20 feet from the center. If the propeller spins at the rate of 1,320 revolutions per second, how many miles will the tip of the blade travel in one minute? (1 mile = 5,280 feet)
Choose the correct answer:	A) 200π	B) 240π	C) 600π	D) 480π	E) 1,200π
Distance traveled in 1 revolution = 2πr= 2π20/5280   Revolutions in one second= 1320   Revolutions in 60 seconds (one minute)= 1320*60   Total distance traveled= total revolutions *distance traveled in one revolution   1320*60 *2π20/5280= 600π   600π is the answer
