The average is 130 parts per hour.

Step-by-step explanation:

Given,

Parts being made at factory = 521

521 parts are made in = 4 hours

Average parts per hour = [tex]\frac{Parts\ made}{No.\ of\ hours}\\[/tex]

Average parts per hour = [tex]\frac{521}{4}[/tex]

Average parts per hour = 130.25 parts

Rounding off to nearest whole number

Average parts per hour = 130 parts

The average is 130 parts per hour.
