A stepping motor with 200 step angles is coupled to a lead screw through a gear reduction

Question:

A stepping motor with 200 step angles is coupled to a lead screw through a gear reduction of 5:1 (5 rotations of the motor for each rotation of the lead screw). The lead screw has 2.4 threads/cm. The worktable driven by the lead screw must move a distance = 25.0 cm at a feed rate = 75 cm/min. Determine
(a) The number of pulses required to move the table,
(b) Required motor speed, and
(c) Pulse rate to achieve the desired table speed.
