Answer:
X ball bearings can be produced in 1 hour and 20 minutes
Step-by-step explanation:
Proportions
Proportions serve as an essential method for solving various common challenges. We understand that:
Company ABC manufactures X ball bearings in 3 hours.
Company DEF produces X ball bearings in 4 hours.
Company GHI generates X ball bearings in 6 hours.
In a single hour, each company is capable of producing:
ABC: X/3 ball bearings
DEF: X/4 ball bearings
GHI: X/6 ball bearings
By collaborating, they can produce

ball bearings. Operating together

If their output is 3/4 of a ball bearing in one hour, then it will take
hours to create one complete ball bearing. This translates to 1 hour and 20 minutes.
X ball bearings can be produced in 1 hour and 20 minutes
Step-by-step explanation: We have the dimensions of a rectangular field given in feet. We are informed that an extension of

feet is made to each side. Therefore, the new dimensions can be calculated accordingly. Hence, they are presented as .
