HELP PLEASEEEEEEEEEE

Answer 1

11:50 AM

Explanation:

We should first find the sum of the times it would take her to clean each room, along with the break time.

Kitchen = 80 minutes
Lounge = 40 minutes
Bedroom = 90 minutes
Bathroom = 35 minutes
Break = 45 minutes

`\text{Total time (in minutes) } = 80 + 40 + 90 + 35 + 45 = 290.`
We should then divide this amount of minutes by 60 to find how many hours it took her.

`\text{Total time (in hours) } = (290)/(60) = 4\frac56`
This means it took her 4 hours and 50 minutes to finish cleaning.

Therefore, if she started working at 7 AM and worked for 4 hours and 50 minutes, she was done by 11:50 AM.
