Acheetah can run at a maximum speed 97.8 km/h and a gazelle can run at a maximum speed of 78.2 km/h. if both animals are running at full speed, with the gazelle 96.8 m ahead, how long before the cheetah catches its prey? answer in units of s. the cheetah can maintain its maximum speed for only 7.5 s. what is the minimum distance the gazelle must be ahead of the cheetah to have a chance of escape? (after 7.5 s the speed of cheetah is less than that of the gazelle.) answer in units of m.
