There is a dam with a volume of 49 cubic metres. Water flows out of this into one of the creeks. Salt water with salt content of 30kg/m3 flowed into the dam at 0.68m3/s and mixed with the fresh water. The mixed water flowed out at the same rate. Flag tail in the dam can tolerate salinity up to 14kg/m3. How long after the flow starts can the fish survive in the dam?

volume = 49 cubic meter salt content = 30 kg/cubic meter rate of water flowed into the dam = 0.68 cubic meter/sec maximum salinity = 14 kg/cubic meter

You can solve for t using V=49m^3, C_0=30kg/m^3, Q=0.68m^3/s and C=14kg/m^3.
