To calculate the total points that Charles de Vendeville earned, we can use the formula based on the scoring rules:
- He earned 2 points for each second he stayed underwater.
- He earned 1 point for each meter he traveled.
Step 1: Calculate points for time underwater
The time he stayed underwater was 68.4 seconds. Points for time = \( 2 \times 68.4 = 136.8 \) points.
Step 2: Calculate points for distance traveled
The distance he traveled was 60.2 meters. Points for distance = \( 1 \times 60.2 = 60.2 \) points.
Step 3: Calculate total points
Total points = Points for time + Points for distance
Total points = \( 136.8 + 60.2 = 197.0 \) points.
Therefore, Charles de Vendeville earned a total of 197.0 points.
