1.) Conveyor Race

The box of gears will pass the box of timing belts 6 minutes and 40 seconds after the box of motors passed the box of timing belts.

2.) Fuse Ruse

They shipped four boxes of 17 and two boxes of 16 – for a total of exactly 100 fuses.

3.) Paint Match

40 widgets can be assembled and painted by the robot in one shift.

Let X represent the  unknown quantity of widgets.  The faction of the shift spent assembling widgets would be:  x widgets divided by 65 widget/shift, and likewise the fraction of the shift spent painting would be  x widgets divided by 104 widgets/shift.  The two fractions total 1 shift, so x/65 + x/104 = 1; x=40
