Hard word problem

Solve the following word problems using positive and negative numbers.

Find the difference in height between the top of a hill 973 feet high and a crack caused by an earthquake 79 feet below sea level.

Respuesta :

As top of hill means a positive value so, 973 feet.

As crack means below or lower, it has negative value so, -73 feet.

As we know that Difference means the subtraction of two numbers, so,

[tex]973 - ( - 73) \\ = > 973 + 73 \\ = > 1052 feet[/tex]

Therefore, the difference in height between the top of a hill 973 feet high and a crack caused by an earthquake 79 feet below sea level is 1052 feet.
