You have 2 boxes of 21 parts. On average, each individual work operation takes 3 minutes per part. At the end, packaging the entire box as required takes 10 minutes. About how long should it take you to get all of the work done? *

2 hours, 26 minutes

Step-by-step explanation:

2 boxes of 21 parts = 42 total parts

3 minutes per part = 42 x 3 = 126 minutes

10 minutes per box to package = 10 x 2 = 20 minutes

126 + 20 = 146 minutes

2 hours = 120 minutes

146 - 120 = 26

Final 2 hours, 26 minutes

if i put something wrong your not gonna like it so rather not say nothing.
