A man can drink a barrel of beer in 27 days. A woman can drink a barrel of
in 54 days.
If they both drink from the same barrel at their respective rates,
how long will it take for the barrel to be emptied?
Answer
If it takes a man 27 days to drink one barrel, he drinks 0.037 of a barrel
each day. Similarly, a woman drinks 0.0185 of a barrel each day. Added
together, a day's combined drinking consumes 0.0555 of a barrel. In this
case, to drink the whole barrel takes 18.018 days
