Here we convert the 1 hour into seconds and the given time is 9 seconds.
We convert the kilometres into meters then we can easily solve it.
3600/9 = 6000/x.
x = 150m.

They are given speed in terms of km/hr,
Hence we have to convert that unit into m/hr because of all the 4 options are in terms of *meter and they are asking us the length in * 9 seconds.
After we convert in terms of m/s, then just we have to multiply the value we have converted (m/s) with 9 seconds.
I hope you will understand.
