Aswimming pool can be filled in 1818 hours if water enters through a pipe alone, or in 2525 hours if water enters through a hose alone. if water is entering through both the pipe and the hose, how long will it take to fill the pool?

Total Time = (pipe time * hose time) / (pipe time + hose time)
Total Time = (18 * 25) / (18 + 25)
Total Time = 450 / 43
Total Time = 10.465116 hours
