It should take 5.22 minutes to clean a shower.you have 5 showers that need to be cleaned.How many minutes should it take for you to clean all 5 ?

Answer 1

To answer this question, first write down what you know in your own words:

1. We need to clean five showers
2. It takes 5.22 minutes to clean a shower.

The most important thing we know here is that it takes 5.22 minutes to clean ONE shower so we can write a proportion: minutes per shower(minutes means the minute it takes to clean) so we can rewrite it as 5.22 minutes per one shower, or 5.22 minutes/1 shower.

Now what are we looking for? How long it takes to clean five showers so our next proportion is x minutes/ 5 showers. Lucky for us, we can set proportions equal to each other and cross multiply

5.22 minutes = x minutes

1 shower 5 shower

cross multiply and we have (5.22)(5)=x

x=26.1
