To calculate the velocity, we use the formula:
\[ \text{Velocity} = \frac{\text{Distance}}{\text{Time}} \]
Given:
- Distance \(d = 400\) meters
- Time \(t = 35\) seconds
Plugging in the values:
\[ \text{Velocity} = \frac{400 \, \text{m}}{35 \, \text{s}} \]
\[ \text{Velocity} = 11.43 \, \text{m/s} \]
So, Bipison's velocity is \(11.43 \, \text{m/s}\).
