Question 1014958
There are 20 rollers under a conveyor belt and each roller has a radius of 15 inches. The rollers turn at a rate of 50 revolutions per minute. What is the linear velocity of the conveyor belt?
---------------
The number of rollers is not relevant.

The circumference is 2*pi*r = 30pi inches = 2.5*pi feet
@ 50 rev/min --> 50*2.5*pi ft/min
--> 50*2.5*pi/60 ft/sec
=~ 65.4 ft/sec
