swimming pool Theflow rate for one pipe is 1 1/4 that of another pipe. A swimming pool can be filled in 5 hours using both pipes. Find the time to fill the pool only using the pipe with the lower flow rate.

The pipe with the lower flow rate can be used to fill the pool by itself in 5 x (1/1.25) = 4 hours. This is because the flow rate of the pipe is 1/1.25 (or 0.8) times slower than the other pipe, so without the other pipe, it would take longer to fill the pool.
