Tanya and tim clean the house in 3 hours their 3 children at the same 6 hours
zheka24 [161]

It will take them exactly 4hours 48 minutes.

<h3>what is rate?</h3>

Rate is a measure of a given quantity against a known or standard quantity.

Analysis:

If Tanya and Tim cleaned the house in 3 hours. Then either of them would clean the house in 2 x 3 = 6 hours.

If their 3 children cleaned the house in 6 hours, then each child would clean the house in = 3 x 6 = 18 hours

Total time for cleaning the house = 18 hours + 6 hours = 24 hours

If the five people were to do it at once then time taken to clean the house = 24/5 = 4.8 hours = 4 hours 48 minutes

In conclusion, the time for 5 people to clean the house is 4 hours 48 minutes

You replace each x with 3

5(3)+9(3)

That 3 right next to the five means you multiply not add.

15+27=42
