Working together, two pumps can drain a certain pool in
hours. if it takes the older pump
hours to drain the pool by itself, how long will it take the newer pump to drain the pool on its own?
New pump = (14 * 6) / (14 -6)
New pump = (84) / (8)
New Pump = 10.5 hours
Two pumps can drain a certain pool in 6 hours.
So, the combined one hour work of the pumps = ,
Also,older pump takes 14 hours to drain the pool by itself,
The one hour work of older pump = ,
Thus, the one hour work of newer pump = Combined one hour work - one hour work of older pump,
Hence, the total time taken by newer pump =
