Question

It takes 120 minutes to weed a garden with 6 gardeners If the same work is to be
done in 30 minutes, how many more gardeners are needed?​

Answer 1

Answer:

120 minutes = 6 gardeners

= 1 gardener = 120/6 = 20 mins

Therefore, 30 minutes = 30/20 = 3/2 = 1.5 gardeners

= 2 gardeners (By Estimating)

Therefore, 2 more gardeners for wedding the garden are needed and in total, 8 gardeners.

Answer 2

Answer:

18 more gardeners.

Step-by-step explanation:

The given question states that for the 6 gardeners it takes 120 minutes to weed a garden. So, each gardener completes the work in 120*6=720 minutes.

So, now for completion of the task in 30 minutes we will be needing 720/30=24 gardeners to do the job.

So, 24-6=18 more gardeners are required to weed the garden in 30 minutes.
