The hydrаulic cоnductivity оf sоil is meаsured аs 4 x10-2 cm/sec. After an accident, a truck carrying dissolved salt solution releases its contents to the surface. The distance between the spill and a groundwater well is 1600 meters. The groundwater elevation at the spill location is 9.3 meters and the well location is 5.3 meters. The porosity of the soil is 0.15. Considering the seepage velocity, the travel time of contaminant to the well is most nearly (days):
