Question

A tree casts a shadow 24 feet long. a 5 foot person casts a 8 foot shadow.How tall is the tree?

Answer 1

(length of tree's shadow)/(height of tree) = (length of person's shadow)/(person's height)

24/x = 8/5

24*5 = x*8

120 = 8x

8x = 120

8x/8 = 120/8

x = 15

The tree is 15 feet tall
