Answer 1

To find the dog's average speed, we use the formula for speed, which is:

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

In this case, the distance is 180 meters and the time is 60 seconds. Plugging in these values:

\[
\text{Speed} = \frac{180 \, \text{meters}}{60 \, \text{seconds}} = 3 \, \text{m/s}
\]

Therefore, the dog's average speed is indeed 3 m/s.

The student answered correctly, so the appropriate response would be:

**Yes**.
