A recent forest fire near Littleville destroyed twofifths of the trees in Bigtree National Forest. The forest covers 3120 km^{2}. There is now about 40 tons of salvageable wood per km^{2} in the burned area. The part of the forest that was not destroyed by fire will not be open to the salvagers. Assuming the trees are evenly distributed throughout the park, about how long will it take to remove all the salvageable wood at a rate of 60 1/3 tons per day? Round your answer to the nearest whole number.
