Final answer:
The clouds are 6900 feet above sea level, which is found by adding the 200 feet needed to reach sea level to the 6700 feet the fish must travel upward to reach the clouds.
Step-by-step explanation:
The question involves calculating how many feet above sea level the clouds are, based on the information that a fish is at a depth of 200 feet below sea level and needs to travel 6700 feet to reach the clouds. To find the altitude of the clouds, we need to add the distance the fish travels to reach sea level (200 feet) to the distance from sea level to the clouds (6700 feet): 200 feet + 6700 feet = 6900 feet above sea level. Therefore, the clouds are at an altitude of 6900 feet above sea level.
