WikiJob solutions test #2

WikiJob
#1

Hi everyone,

Noticed some possible mistakes in the numerical test #2:

  1. Spur gears produced - Isn’t the max. difference of pieces per hour = 3*(3+3+5+10+14) - 3*(0+0+0+5+7) = 69? You assume that more than one operator can use one machine at the time.
  2. Regarding the speed limits and the transportation companies - Shouldn’t be the answer 21:26:30?

And could anyone please explain the wage bill change in test #1?

thx
