Question

A fishing hook is at an elevation of −12 m relative to sea level. Half an hour later, the fishing hook's elevation increases by 12 m. Which equation represents this situation?

Answer 1

Answer:

$-12m + 12m =0$

Step-by-step explanation:

Given

$Initial\ Position = -12m$

$Rise = 12m$

Required

Represent as an equation

The new position of the hook is calculated by:

$New\ Position = Initial\ Position + Rise$

This gives:

$New\ Position = -12m + 12m$

$New\ Position = 0$

Hence, the equation is:

$-12m + 12m =0$
