Question

Sally begins hiking at an elevation of 224 ft then she descends 131 ft and climbs 67 feet higher than her current position she then descends 163 ft write an addition sentence to describe the situation then determine and interpret the sum

Answer 1

Sally ends at 3 feet below zero point.

Explanation:

Let be
`h` the height with respect to zero point, which is represented by the following sum:

`h = \Sigma_(i=1)^(n) h_(i)`

Where:

`h_(i)` - i-th travelled height, measured in feet.

In addition, positive sign means ascension, whereas negative sign means descent.

The statement can be translated into the following mathematical identity:

`h = h_(1)+h_(2)+h_(3)+h_(4)`

`h = 224\,ft+(-131\,ft)+67\,ft -163\,ft`

`h = -3\,ft`

Sally ends at 3 feet below zero point.
