Pedro can finish a table for about 3 hrs and Juan is 2 hrs if they will combine how long they can finish a table?
P does 1/3 of the job per hour.
J does 1/2 per hour.
Together, they do 1/3 + 1/2 per hour = 5/6 per hour
--> 6/5 hours per job

please help me to get the right formula.
Knowing how to do it is important. Knowing a formula, if there is one, is not.
