"it takes 3 hours for two people to complete a particular job working together. If one of them could have completed the job alone in 8 hours, how long would it take the other to complete the job working alone?"
together they do the job in 3 hours
so 1/3 of job they do in 1 day
.
one does in 8 hours
so he does 1/8 of job in 1 hour
1/3 - 1/8 = 5/24 is the job done by the other person
So for 1 job the second person will take 24/5 hours
= 4.8 hours
