Question

In sunlight, a vertical stick has a height of 5 ft and casts a shadow 3 ft long at the same time that a nearby tree casts a shadow 15 ft long. How tall is the tree?

Answer 1

since the length of the shadow of the tree is 5 times longer ( 15/3 =5)

multiply height ( 5) x 5 = 5*5 = 25

so height of tree is 25 feet tall
