Question

Shelley cleans out houses. She worked 18 hours cleaning 5 different houses. She worked an equal number of hours at each house. How many hours did Shelly work at each house?

Answer 1

The amount of time it takes Shelly to clean each house is 3.6 hours or 2 hours 36 minutes.

Explanation:

Shelly cleans 5 different houses in 18 hours.

To compute the amount of times Shelly spends cleaning one house divide the total hours spend by the number of houses cleaned.

The number of hours it takes Shelly to clean a single house is:

Number of hours spent cleaning 1 house =
`(18)/(5)=3.6` hours.

Thus, the amount of time it takes Shelly to clean each house is 3.6 hours or 2 hours 36 minutes.
