Question

it takes two painters five hours to finish painting a house how long would it take to finish painting your house if they were 20 painters working at the same time

Answer 1

Answer:0.5 hours

Explanation:

Given

It takes two painters 5 hrs to finish painting a house

Here, no. of painters and no. of working hours are inversely related

So,
`\text{no. of Painters}* \text{no. of working hours=work}`

Work is the same in both the cases

`2* 5=20* \text{no. of working hours(x)}\\x=(10)/(20)=0.5\ \text{hrs}`
