To calculate the distance traveled by the dolphin, you can use the formula:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
Given:
- Speed = 1.85 m/s
- Time = 6.0 s
Now, plug the values into the formula:
\[ \text{Distance} = 1.85 , \text{m/s} \times 6.0 , \text{s} = 11.1 , \text{m} \]
Since the closest option to 11.1 m is 11 m, the answer is:
a) 11 m
