will the workers take to dig a canal of length 140
metres, breadth 4 metres and depth 2.5 metres
if they work 8 hours per day.

Answer 1

Answer:

If a worker can dig 1 meter per day, then the project will take 3 meters/1 meter per day = 3 days

Step-by-step explanation:

Okay, so 16 workers dig 80 meters in 5 days, right.

First, let's think about how much work each worker did:

80 meters/16 workers = 5 meters per worker

Next, it took each worker how long to do this?

5 meters / 5 days = 1 meter per day. A worker can dig one meter per day.

So if you have 24 workers who can dig 1 meter per day, how many days will it take them to dig 72 meters?

72 meters/24 workers = 3 meters per worker
