An environmental protection group is monitoring a river to determine the cause of a fish kill. A steel mill releases hot water into the river every 80 hours, and a plastics plant discharges pollutants into the river every 250 hours. If
both hot water and pollutants from the plastics plant have just been discharged, in how many hours will both be
released into the river again?
Both hot water and pollutants from the plastics plant will again be released into the river at the same time in
hours. (Type a whole number.)
