Question 328655: A wheel revolves at a rate of 40 revolutions per second. If the radius of the wheel is 2/pi feet, how far will the wheel travel in 2 minutes? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! radius of wheel = 2/pi feet
circumference = 2*pi*r
=2*pi*2/pi
=4 feet
..
40 revolutions / second
one revolution it covers 4 feet
40 revolutions it will cover 40*4= 160 feet.
= 160 feet/second
..
2minutes = 120 seconds
1 second 160 feet
120 seconds ?
160*120=19200 feet in 2 minutes
