Figure 1 shows a precision linear actuator system. 'Drive Gear D', which has 16 teeth, is meshed with 'Idler Gear I', which has 40 teeth. 'Idler Gear I' is further meshed with a horizontal 'Linear Rack'.
As the gears turn, the rack translates horizontally. The teeth on the rack are spaced 1.75 mm apart.
Calculate how far the linear rack moves when Drive Gear D completes exactly 1.5 full revolutions.
