A cheetah can run at a maximum speed
103 km/h and a gazelle can run at a maximum speed of 74.3 km/h.
If both animals are running at full speed,
with the gazelle 57.5 m ahead, how long before
the cheetah catches its prey? Answer in 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.

1. distance = speed * time
when are the two distances equal? The cheetah has to run an extra 57.5m
