Question 1070268: Two pulleys, one with radius 1 inch and the other with radius 6 inches, are connected by a belt. If the 1-inch pulley is caused to rotate at 400 revolutions per minute, find the linear speed (in feet per second) of the belt which is the same as the linear speed of both pulleys and determine the revolutions per minute of the 6-inch pulley.

.
The linear speed of the belt is 2%2Api%2Ar%2An = 2%2A3.14%2A1%2A400 = 2512 inches/minute.

The number of revolution per minute of the 6-inch pulley is 400%2F6 = 66.666. . . per minute.
