Question

Altitude above sea level is given in positive values and below 4 sea level is given in negative values. Which situation describes a hiker in Death Valley stopping at an altitude of O feet?

Answer 1

We have four situations about a hiker and we have to choose the correct.

As the positive altitude values are above the sea and negatives are below the see, the correct answer is the third becuase the hiker could be at -10 feet and need to increase the altitude by 10 feet to reach 0 feet.
