All the members of a construction crew work at the same pace. four of them working together are able to pour concrete foundations in 32 hours. how many hours would this job take if the number of workers: increased 2 times increased 4 times

1) Increased by 2 times then 16 hours

2) Increased by 4 times then 8 hours

Step-by-step explanation:

Given :-

==> 4 construction crew members need 32 hours to pour concrete foundations.

==> All the members work at a same pace.

1) If the numbers of workers are increased by 2 time i.e., 4 workers × 2 = 8 workers. It would take half of the time that is taken now i.e., 32 hours ÷ 2 = 16 hours.

2) If the numbers of workers are increased by 4 time i.e., 4 workers × 4 = 16 workers. It would take 1/4th of the time that is taken now i.e., 32 hours ÷ 4 = 8 hours.

ou would have 12 of each
