Number of widgets that can be made by Machine X in 1 hour = 40/8 = 5 
Number of widgets it can make in 1 hour = 5*60 = 300

Answer D

ScottTargetTestPrep · Answer

Since 1 hour is 60 minutes, Machine X can make 40/8 x 60 = 5 x 60 = 300 widgets.

Alternate solution:

We can set up a proportion in which x is the number of widgets that can be made in 1 hour, or 60 minutes:

40/8 = x/60

5 = x/60

300 = x.

Answer: D
