Final answer:
The cat walked at a speed of 1.91 m/s.
Step-by-step explanation:
To find the speed at which the cat walked, we need to divide the distance it walked by the time it took. In this case, the cat walked 8.4 m in 4.4 seconds. So the speed of the cat is calculated as:
Speed = Distance / Time = 8.4 m / 4.4 s = 1.91 m/s
Therefore, the cat walked at a speed of 1.91 m/s.
