Answer:
The correct answer is 30 feet.
Explanation:
1. Let's check all the information given to answer the question properly:
Distance from the platform to the water = 16 feet
Distance reached by the diver below the water's surface = 7 feet
2. Let's calculate the total distance the diver covered in the dive:
First distance : from the platform to the water
This distance is 16 feet
Second distance : from the water's surface to the depth of the pool or sea
This distance is 7 feet
Third distance: from the depth of the pool or sea to the water's surface
This distance is 7 feet. The diver will need to breath again after some seconds and will start to go up to the surface immediately.
Total distance = 16 + 7 + 7 = 30 feet.
