An empty swimming pool is filled by two inlet pipes. On pipe can fill 1 & 1/10 of the swimming pool in one hour. The other can fill 1/8th of the swimming pool in one hour. If both inlet pipes are used to fill the pool, how many hours will it take to fill the empty pool?
----
Together rate = 1.1+1/8 = 1.225 pools/hr
-----
Time to fill = 1/1.225 = 0.8163 hrs = 0.8163*60 min = 41 minutes
