Nadia is mountain climbing. She started at an altitude of 19.26 feet below sea level and then changed her altitude by climbing a total of 5,437.8 feet up from her initial position. What was Nadia’s altitude at the end of her climb?
3,511.8 feet above sea level
5,245.2 feet above sea level
5,418.54 feet above sea level
5,457.06 feet above sea level
To find Nadia's altitude at the end of her climb, we add her initial altitude to the distance she climbed:
Altitude at the end = Initial altitude + Distance climbed
Altitude at the end = -19.26 + 5437.8
Using a calculator, we find that the altitude at the end of her climb is 5418.54 feet above sea level.
Therefore, the correct answer is 5,418.54 feet above sea level.
