Answer 1

I don't know correctly about it

Answer 2

Answer:

9 seconds

Explanation:

As given in question,

Speed of cheetah, v = 160 km/h

                              $=\ \dfrac{160\times 1000}{3600}$

                              = 44.44 m/s

Distance covered by the cheetah, d = 400 m

According to the definition of speed, speed can be given by

  $Speed\ =\ \dfrac{distance}{time}$

$=>\ time\ =\ \dfrac{distance}{speed}$

               $=\ \dfrac{400}{44.44}$

               = 9 sec

So, to cover the distance of 400 m with the speed of  160 kmph the cheetah will take a time of 9 seconds.
