Jack was planting a tree. He was to dig a hole that was 3 feet deep for every 5 feet of tree height. How deep should he dig the hole for a tree that is 17feet high.

Calculations

$\frac{DEEP}{HIEGHT}$

Cross multiplication

$\frac{3 DEEP}{5 HIEGHT}$ = $\frac{x}{13}$

5x = 2 x 13

Divide by 5 to isolate x

$\frac{5x}{5}$ = $\frac{51}{5}$

x = 10.2

Answer = 10.2
