If the drive sprocket has a diameter of 4.2 inches, the driven sprocket connected to the gear box has a diameter of 8.7 inches, and the gear box itself has a gear ratio of 50:1. What is the output RPM if the motor is running at 1000 RPM?

if u have the diameter of the sprocket of both the driven and the drive, rpm of motor and the ratio of the gearbox, then
rpm of the driven sprocket= diameter of the drive sproket x rpm of the main motor divided by the diameter of tne driven sproket.
output of the gearbox: 50 divided for rpm of the driven sproket.
