Tap 1 fills (1/10)th of the tub in a minute
Tap 2 fills (1/15)th of the tub in a minute
Tap 3 fills (1/30)th of the tub in a minute
(1/10)+(1/15)+(1/30)=(3/30)+(2/30)+(1/30)=(6/30)
The three taps will fill the tub in 30/6=5 mins
This is an impressive answer. Congrats.
Thank you
If John opens all 3 taps, the bath would fill in 5 minutes.

me realising that 1/6 is not the same as 1/3 ('o')
You did it the hard way. I just assumed the bath is 30 gal.
