A deep-sea diver is 4.5 m below the water level. At what depth is he now? At what height is he now?
4.5m depth -4.5m height
looks like 4.5 for depth, -4.5 for height
To determine the current depth and height of the deep-sea diver, we need to know the reference point from which these measurements are taken. Assuming the water surface level is considered as the reference point, we can calculate the depth and height.
Since the diver is 4.5 meters below the water level, we can say that the current depth is -4.5 meters. The negative sign indicates that the diver is below the water surface.
To find the height, we need to consider the distance from the reference level (the water surface) to the diver. Since the diver is below the water surface, the height will be negative as well. So, the height can be calculated by subtracting the depth from zero.
To summarize:
- Depth: -4.5 meters
- Height: 0 meters - (-4.5 meters) = 4.5 meters
Therefore, the diver's current depth is -4.5 meters, and the diver's current height is 4.5 meters.
