Solution:
Given: cheetah runs in constant speed.
In 4 seconds cheetah covers 120 meters.
Hence,
The speed at cheetah runs = distance/time = 120/4 = 30 m/s
Now, at 25 seconds,
Distance covered by cheetah after 25 seconds = time x speed = 25 x 30 = 750 meters
Now, when cheetah covered 270 meters, the time required to cover 270 meters = distance / speed = 270 / 30 = 9 seconds
