hi. it is the question of acceleration
and not proper information is given. i can solve it considering uniform motion
but our teacher gave only this much

Hi,
Cheetah can run at 100 km/hr
Converting into M/s i.e 100 *1000/ 3600 as 1 hour =3600 sec
we get 27.7777 m/sec
So now the prey is 100 m far
Dividing 100/27.77
We find that cheetah will reach its prey in 4 seconds

we know that
1 km/hr=5/18 m/sec
so , 100 km/hr=100x5/18 m/sec
=27.78 m/sec
as we know .,,,
speed= distance/time
or , time=dist/speed
=100/27.78 sec
=3.59 sec answer
