The correct option is A Cat
To find which animal is faster, we need to find the number of feet they cover per second.
Speed at which the cat runs = 3 ft per s
Distance covered by the rat in 2 s = 5 ft
Speed at which the rat runs = distance covered in 1 s = 52 = 2.5 ft per s
Comparing the rate at which the cat and rat run, we can see that the cat is faster.
