Question

If Dominik completes a project by himself, it will take him 8 hours. Working with Katarina, it will take them 5 hours. If they work together, what is the missing value from the table that represents the part of the project Dominik will complete? 8r 8(5) r (5)

Answer 1

There is a formula for this
Time for Katarina = (Dominick's Time * Total Time) / (Dominick's Time - Total Time)
Time for Katarina = (8 * 5) / (8 -5)
Time for Katarina = 40 / 3
Katarina's Time = 13.3333 hours
