If Dominik completes a project by himself, it will take him 8 hours. Working with Katarina, it will take them 5 hours. If they w
Marysya12 [62]
The main formula we use here is Work=Rate*Time,


1. The rate (speed of working) of Dominik is 

r_D=1project/8hours= \frac{1}{8}(prj/h)

2. Let the the rate of Katarina be r_K=x(prj/h)

Together they have a rate of r_D_K equal to \frac{1}{8}+x (project per hour)

so (\frac{1}{8}+x) ( \frac{proj}{hr})*5(hr)=1(proj)

simplify the units:

(\frac{1}{8}+x) *5=1

\frac{1}{8}+x = \frac{1}{5}

x= \frac{1}{5}- \frac{1}{8}= \frac{8-5}{40}= \frac{3}{40}

so the rate of Katarina is 3/40 (proj per hour)

Now, the rate of Dominik was 1/8 (pr/hr)=5/40 (pr/hr)

In 5 hours Dominik complets 5*5/40=25/40 of the project

Katarina completes 5*3/40=15/40 of the project.
