Answer 1

How long will it take them to clean the bedroom? 10 minutes

How to calculate the time of the work done together?

Given:

Vanessa  (A)= 30 minutes

Steven (B) = 15 minutes

The total time taken if both work together is given by,

             $A+B=\frac{AB}{A+B} \\\\=\frac{30*15}{30+15}\\\\=\frac{450}{45}\\\\= 10$

So, it would take 10 minutes to clean the bedroom, if they work together
