I can solve it by formula, and you can put it into a table.
You have to add their rates of working to get their
rate of working together.
Scientist's rate:
( 1 dose ) / ( 4 hrs )
Igor's rate:
( 1 dose ) / ( 12 hrs )
------------------
Let = the time in hrs for them to make 1 dose
working together.
Multiply both sides by
Working together they can make 1 dose in 3 hrs
