Starting from a trail 1.0m above the water level, you climb straight up a cliff to a point 15m above the water. You then shallow dive into the water and climb back to the trail. Find your displacement (Δx) as well as the distance (d) you covered (not including the swim).

Consider the positive x-direction to be up.

Δx= 0 m
d= 31m

Is this right?

yes, If you end up where you started, your displacement is zero.

14 climb + 15 dive + 1 climb = 30

from 1 meter above water to 15 meters above water is 14
