Question

A recent forest fire near Littleville destroyed four-fifths of the trees in Bigtree National Forest. The forest covers 4920 km^2. There is now about 30 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 53 1/2 tons per day? Round your answer to the nearest whole number.

Answer 1

area destroyed = (3/4)(4920) km^2 = 3690 km^2
tons of wood available = 90(3690) tons = 332100 tons
at a rate of 53.5 tons/day to remove the wood,
time taken = 332100/53.5 days = 17 years ?????

unreasonable question!

Answer 2

The answer is 552 days
