Question

Hannah and James are married. Every Saturday they take turns to clean their apartment. Hannah cleans it

fast in 3 hours because she does not like to clean. James listens to music, texts, and takes his time while
cleaning. He takes 5 hours. They finally decided to do it together. How long will it take?

Answer 1

1 7/8 hours

Explanation:

x/3+x/5=1

5x+3x=15

8x=15

x=1 7/8 hours

Answer 2

4 hours

Explanation:

I found the average

(3+5)/2

8/2 = 4

This is probably wrong because logically it wouldn't make sense for them to take longer than 3 hours if two people are cleaning but i dont know
