MATH PUZZLE #2
Friday, June 23, 2023 3:55 PM
it's a long day at work and lunch time hasn't even arrived yet.
i posted one of these puzzles several months ago so i figured why not now for #2. this one popped up on the youtube site. it's a cool one. anyway here goes:
alice and bob can complete a job in 2 hours
alice and charlie can complete the same job in 3 hours
charlie and bob can complete a job in 4 hours
how long would the job take to be completed if all 3 worked together?
