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

Respuesta :

Answer:0.5 hours

Step-by-step 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, [tex]\text{no. of Painters}\times \text{no. of working hours=work}[/tex]

Work is the same in both the cases

[tex]2\times 5=20\times \text{no. of working hours(x)}\\x=\dfrac{10}{20}=0.5\ \text{hrs}[/tex]
