Question

If three workers can paint a room in two hours and approximately how long does it take for workers to paint the same room assume the time needed to paint the room is inversely proportional to the number of workers

Answer 1

The time taken by the four workers to paint the room is 1.5 hours.

Explanation:

3 workers can paint a room in 2 hours

So, 1 worker can paint the same room in 6 hours.

Now the number of workers is 4.

So, the time in which the 4 workers can paint the same room is

= 6/4 = 1.5 hours
