Cheetah is the fastest land animal and can achieve a peak velocity of 100 km/hr up to a distance less than 500m. If a cheetah spots it's prey at a distance of 100m, what is the minimum time it will take to get it's prey, if the average velocity attained by it is 90 km/hr?

If the cheetah spots the prey at its top speed, the cheetah will hunt down the prey with the speed of 100 If the cheetah spots the prey at its top speed, the cheetah will hunt down the prey with the speed of 100km .
velocity = 90km/h
=90×1000/3600
=25m/s
d= 100 m
t = d/v
=100/25
=4sec
So, the minimum time the cheetah will take to get the prey is 4 s.

Hey there!
It's given,
A cheetah is the fastest land animal and it can achieve a peak velocity of 100 km per hour up to distances less less than 500 metres.
We can write 100 km as 27.78 m/s. [100x1000/60x60]
We know,
Formula to calculate speed:
Speed (v) = Ditance/time (d/t)
∴ Time = Distance/Speed (d/v)
= 100/27.78
= 3.6 s
∴ The minimum time it will take to get it's prey is 3.6 second.
Hope it helps You!
