Answer: City A is 34,281 feet higher that City B.
Step-by-step explanation:
You know that:
- City A has an elevation of 15,723 feet above sea level.
- City B has an elevation of 18,558 feet below sea level.
The sea level is: 0 feet. Therefore, to calculate how much higher is City A than City B you must add both quantities, because from the City B to the sea level there are 18,558 feet and from the sea level to the City A there are 15,723 feet.
Then:
15,723 feet+18,558 feet=34,281 feet
