To calculate the total points earned by Charles de Vendeville, we need to apply the scoring system described:
- Each second underwater earns 1 point.
- Each meter traveled earns 2 points.
We are given the following values:
- Time underwater: 68.4 seconds
- Distance traveled: 60.2 meters
Now we can calculate the points earned:
Points from time underwater: \[ \text{Points for time} = \text{Time (seconds)} \times 1 = 68.4 \times 1 = 68.4 \text{ points} \]
Points from distance traveled: \[ \text{Points for distance} = \text{Distance (meters)} \times 2 = 60.2 \times 2 = 120.4 \text{ points} \]
Total points: \[ \text{Total points} = \text{Points for time} + \text{Points for distance} = 68.4 + 120.4 = 188.8 \text{ points} \]
Thus, the total points earned by Charles de Vendeville to place first is 188.8 points.
So the correct response is: 188.8 points
