The end of a blade on an airplane propeller is 15 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)	Pick:
A) 200π  B) 240π  C) 300π  D) 450π  E) 1,200π
450πistance traveled in 1 revolution = 2πr= 2π15/5280   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 *2π15/5280= 450π   450π is the answer
