To find the tiger's speed, you can use the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
Here, the distance is 540 meters and the time is 36 seconds.
Now, plug in the values:
\[ \text{Speed} = \frac{540 , \text{m}}{36 , \text{s}} = 15 , \text{m/s} \]
Thus, the tiger’s speed is 15 m/s.
