Question

It takes 15 men working steadily 4 days to dig the foundation for a new apartment. How many days would it have taken 25 men working at the same rate to dig the foundation? Express your answer as a decimal to the nearest tenth.]

Answer 1

2.4 days is the answer.

Explanation:

It takes 15 men working steadily 4 days to dig the foundation for a new apartment.

Let 25 men takes 'x' days to complete the same task.

Applying ratio we get:

`(15)/(25) =(x)/(4)`

Solving this we get;

=>
`25x=60`

So, x = 2.4 days
