Answer 1

To find the fastest speed of the dolphin, we can use the formula for speed:

\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

In this case, the distance is 1,000 meters and the time is 66.7 seconds. Plugging in the values:

\[ \text{Speed} = \frac{1000 \, \text{m}}{66.7 \, \text{s}} \]

Calculating that:

\[ \text{Speed} \approx 15 \, \text{m/s} \]

So the fastest speed of a dolphin is **15 m/s**.
