Question

If a 10 ft tall adult elephant casts a 2 ft long shadow, then how tall is a statue that casts a 3 ft shadow?

Answer 1

Given data:

The given height of the elephant is h=10 ft.

The given shadow of the elephant is s=2 ft.

The shadow of the elephant from the height is,

$\begin{gathered} \frac{s}{h}=\frac{2}{10} \\ =\frac{1}{5} \end{gathered}$

Mulitiply 3 on both sides on right hand side.

$\begin{gathered} \frac{S}{H}=\frac{3}{3(5)} \\ =\frac{3}{15\text{ }} \end{gathered}$

Thus, 15 feet elephant cast 3 feet shadow.
