Answer: 4 second

To answer this question you need to know the difference between the cheetah and the antelope speed.

It would be: 90 feet/s - 60feet/s = 30 feet/s

That means the distance between the cheetah and the antelope will shorten 30 feet every second. After that divide the distance with the speed difference:

120 feet / (30feet/s) = 4 second
