To calculate the velocity of the horse, we need to use the formula for velocity:
\[ V = \frac{\text{displacement}}{\text{time}} \]
In this case:
- The horse gallops around a 400 m track, which is a loop. Therefore, after completing one full lap, the displacement is 0 m (since it returns to the starting point).
- The time taken to complete one lap is 20 s.
Now, substituting the values into the formula:
\[ V = \frac{0 \, \text{m}}{20 \, \text{s}} = 0 \, \text{m/s} \]
The correct response is:
**0 m/s**
\[ V = \frac{\text{displacement}}{\text{time}} \]
