Question

A cheetah that is running 90 feet per second is 120 feet behind an antelope that is running 60 feet per second. How long will it take the cheetah to catch up to the antelope?

Answer 1

Cheetah Velocity = 90 ft/s

Antilope Velocity = 60 ft/s

Distance between them = 120 ft

Time taken by Cheetah to Catch Antilope  =  Distance between them / Relative Velocity

                                                                    =  120 / (90 - 60)  

                                                                    =  120 / 30

                                                                    =  4 sec

Answer :

Time taken by Cheetah to Catch Antilope is 4 seconds.
