Question

A bird’s nest is $12$ feet above the ground. A mole’s den is $12$ inches below the ground. What is the difference in height of these two positions?

Answer 1

Hint: $1$ Feet = $12$ inches

Step 1: Given:-
Distance of bird’s nest from ground = $12$ feet
Distance of mole’s den from ground = $12$ inches
As the mole’s den is underground so it’s height is considered as negative that is ,
Distance of mole’s den from ground = $-12$ inches
Step 2: We know that $1$ feet = $12$ inches
So the Distance of mole’s den from ground = $-12$ inches = $-1$ feet.
Step 3: See the figure below:-
Difference in height of these two positions
=distance of position of nest – distance of position of den
= $12$ feet $-$ ( $-1$ feet)
= $12$feet $+$ $1$ feet
= $13$ feet

Final Answer: = $12$feet
