Question

A tree casts a shadow 60 feet long. At the same time, a nearby 8-foot post casts a 12- foot shadow. How tall is the tree?

Answer 1

9514 1404 393

Answer:

40 ft

Explanation:

The post is 8/12 = 2/3 as tall as the shadow is long. We expect the same relationship holds for the tree.

tree height = (2/3)(shadow length) = (2/3)(60 ft) = 40 ft

The tree is 40 feet tall.
