Question

A cheetah can run at a maximum speed

95.4 km/h and a gazelle can run at a max-
imum speed of 74.4 km/h.
If both animals are running at full speed,
with the gazelle 83 m ahead, how long before
the cheetah catches its prey?
Answer in units of s.

Answer 1

Step-by-step explanation:

d = v * t, where d is the distance and v is the velocity, t is the time

cheetah

v = 95.4 km/h

gazelle

v= 74.4 km/h

d1 = 83m = 0.083 km

when the cheetah catches the gazelle the distances will be equal

95.4t= 74.4t+0.083

t= 0.00395 h* (3600s/1h) = 14.22 s
