120 कि.मी.

Answer 1

Answer:

Step-by-step explanation:

In 36 seconds it covers 1200 metres

So it's speed in metre/second is

1200/36 = 100/3 m/s.

but here options are in km/h so we have to convert it into km/h

For converting m/s into km/h we have to multiply it by 18/5.

100× 18 ÷{3×5} = 120 km/s.
