Two pulleys, one with radius 2 inches and one with radius 7 inches, are connected by a belt. if the 2 dash inch pulley is caused to rotate at 3 revolutions per minute, determine the revolutions per minute of the 7 dash inch pulley. (hint: the linear speeds of the pulleys are the same, both equal the speed of the belt.)
