--------------
slower tap DATA: time = 10 min/job ; rate = 1/10 job/min
faster tap DATA: time = 15 min/job ; rate = 1/15 job/min
------------------
together DATA: time = x min/job ; rate = 1/x job/min
==================
Equation:
rate + rate = together rate
1/10 + 1/15 = 1/x
-------
15x + 10x = 10*15
25x = 150
x = 6 minutes (time to do the job together)
