Jane is hiking at an elevation of 142 feet above sea level she descends 325 feet into a valley. what is janes Elevation in feet in relation to a second hiker who is 24 feet below sea level?

Given parameters:

Elevation of hiking  = 142ft

Descent of Jane  = 325ft

Height of second hiker  = 24ft below sea level

Unknown:

Jane's elevation relative to the second hiker = ?

Solution:

The sea level here is the reference plane and the elevation here is zero;

   Jane                     142ft                          142ft above sea level    

                                                                ↓ Descent

          Seal level        0ft                            0ft                                 Second hiker

                                                                                                              24ft

                                                                   183ft(below sea level)

The elevation of Jane in relation to the second hiker is 183 - 24 = 159ft below the second hiker.
