Question

A tree casts a show of 15 meters, while a 2-meter post nearby casts a shadow of 3 meters. How tall is the tree?

Answer 1

The tree is 10 meters tall.

Explanation:

The tree's shadow is 5 times longer than the shadow of the post. So the height of the post times 5, which is 10 meters.

15/3=5

5(2)=10

Answer 2

10 meters tall.

Explanation:

If the 2 meter post casts a 3 meter long shadow the ratio

is 3:2 where 3 is the shadow and 2 is the height.

3*5=15

2*5=10
