Using the model given below and the data in the table below, find how long it would take for 75% of the pollution to be removed from Lake Michigan and from Lake Ontario, assuming no new pollutants are added. Superior Michigan Erie Ontario V (km) 12,200 4900 460 1600 Model: Let Q be the total quantity of pollutant in a lake of volume V at time t. Suppose that clean water is flowing into the lake at a constant rater and water flows out at the same rate. dQ immediately mixes with the rest of the water. Then! dt Round your answers to the nearest integer. Michigan: i Assume that the pollutant is evenly spread throughout the lake, and that the clean water coming into the lake Ontario: i years years r (km/year) 65.2 = 158 175 209 -Fe
