−48.5 ft.
To find the diver's elevation when he is 23% of the way down, we can calculate 23% of 97.2 feet:
0.23 * 97.2 = 22.356 feet
Since the diver is descending, the elevation will be negative. Therefore, the diver's elevation when he is 23% of the way down is -22.356 feet, which is approximately -22.4 feet.
So, the correct answer is -22.4 ft.
To find the diver's elevation when he is 2/3 of the way down, we need to calculate the depth of the water he has descended.
First, we calculate 2/3 of the distance to the treasure:
2/3 * 97.2 ft = 64.8 ft
Since the diver is descending, the elevation will be negative. Therefore, the correct answer is:
-64.8 ft.
