Question

Sally begins hiking at an elevation of 224 feet. Then, she descends 131 feet

and climbs 67 feet higher than her current position. She then descends

163 feet. Write an addition sentence to describe the situation. Then determine

and interpret the sum.

Answer 1

-3 feets

Explanation:

Given the following :

Starting point = 224 feets

Then descends 131 feets

Then climbs 67 feets higher than her current position

Then descends 163 feets

Addition sentence to describe the situation :

224feets + (-131)feets + 67feets + (-163)feets

Negative (-) points represents descent

224feets - 131feets + 67feets - 163feets = - 3feets

This means Sally is - 3 feets below her initial position.
