A tree casts a shadow that measures 5 m. At the same time, a meter stick casts a shadow that is 0.4 m long. How tall is the tree?

• Math -

We will solve the problem by proportions.

Let the height of the tree be x, then
x/5 = 1/0.4
Cross-multiply to get
x=5*1/0.4=12.5 m.
Thus the tree is 12.5 m. tall
