Answer 1

To find the diver's elevation when he is \( \frac{2}{3} \) of the way down to the treasure that is 97.2 feet below the surface, you can use the following calculation:

1. Calculate how far the diver has gone down: \[ \text{Distance down} = 97.2 , \text{feet} \times \frac{2}{3} = 64.8 , \text{feet} \]

2. Since the diver is going down, his elevation will be negative: \[ \text{Elevation} = -64.8 , \text{feet} \]

Thus, the diver's elevation when he is \( \frac{2}{3} \) of the way down is −64.8 ft. (negative 64 point 8 ft.).
