Question 256498
Think of this in terms of similar triangles. Tree is 80 ft high, building is 600 ft high, so ratio of 1 to 7 1/2. Distances are in the same ratio. Ant to tree is 120 so ant to building is 7 1/2 times 120. So ant to building is 900 feet. What they want is tree to building, which is ant to building less the 120 feet from ant to tree, so tree to building is 780 feet
