Answer: 16 workers will take 3 days
Explanation:
First write down what the question gives you
Time = k/amount of workers
Then substitute the values
6 days = k/8 workers
Change the subject to solve for k
6 days x 8 workers = k
48 = k
Now solve The question using the found value for k with the rewritten formula
Time = k/amount of workers
? days = k/16 workers
? Days = 48/16
= 3 days
