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

Jasmine can run 4 5/6 miles in 2/3 of an hour. how many miles can she run in one hour
Jlenok [28]

Jasmine can run in one hour is 7.25 miles.

<h3>What is the formula of unitary method?</h3>

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Given that,

Jasmine can run 4\frac{5}{6} miles in \frac{2}{3} of an hour.

\frac{2}{3} of an hour = 4\frac{5}{6} miles

                     = \frac{29}{6} miles

By using unitary method we will find the value of an hour.

1 hour = \frac{\frac{29}{6} }{\frac{2}{3} }

          =  \frac{29}{6} × \frac{3}{2}

          = \frac{29}{4}

1 hour  = 7.25 miles

Hence, Jasmine can run in one hour is 7.25 miles.
