Answer:
The elephants' moat should be 3.2 meters deep.
Step-by-step explanation:
Suppose, the depth of the elephants' moat is [tex]x[/tex] meter.
Width of the lions' moat is 5 meter and width of the elephants' moat is 4 meter.
Given that, the lion’s moat is 4 meter deep.
So, according to the ratio of width and depth, the equation will be.......
[tex]\frac{5}{4}=\frac{4}{x}\\ \\ 5x=4*4\\ \\ 5x=16\\ \\ x=\frac{16}{5}=3.2[/tex]
Thus, the elephants' moat should be 3.2 meters deep.
