Question 22670: Pipe A can fill a swimming pool in 10 hours. Pipe B can fill the same pool in 8 hours. If pipe A and pipe B work together for the first 2 hours and then pipe B stops working, how long will it take pipe A to finish the job? Answer by Paul(988) (Show Source):
You can put this solution on YOUR website! 1/10+1/8=2
4/40+5/40=2
9/40t=2
40t=18
t=0.45
Hence,it will take Pipe A 45 minutes to finish the job by itself.
