Question

A hiker starts at an elevation 80 feet above sea level and hikes to a point 790 feet higher than his starting point. What is the hiker's elevation? A) 710 feet B) 870 feet C) −710 feet D) −870 feet

Answer 1

B

Step-by-step explanation:

The correct answer is B because you have to add 790 and 80 together. This gets you 870. Your answer is positive because it's above sea level. Anything above sea level will be positive and anything below sea level is negative.
