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

`-12m + 12m =0`

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`
