Final answer:
The leaf travels a distance of 12 meters.
Step-by-step explanation:
To calculate the distance traveled by the leaf, we can use the formula:
Distance = Speed x Time
Given that the leaf moves at a speed of 4 m/s and the time for which it moves is 3 seconds, we can substitute these values into the formula:
Distance = 4 m/s x 3 s = 12 meters
Therefore, the leaf travels a distance of 12 meters.
