The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.
How to use inverse proportionality to determine building time of a wall
In this question we must use the definition of inverse proportionality, in which the number of workers (), no unit, is inversely proportional to the building time (), in days.
According to the statement, 6 workers spent 6 days building a wall and there are 24 days left for completion, but 3 more workers entered to reduce building time, which can be represented by the following expression:
In this scenario, the wall can be built in 22 days.
