Convert the given unit to the unit you want to convert.

For example, here km/h should be converted to m/s. So convert the numerator from kilometers to meters and denominator from hours to seconds.

1 km = 1000m

1 hour = 3600 seconds

Here it's 36km divided by 1 hour. So 36 km =36 × 1000m and 1 hour = 3600 seconds.

Then apply to the original equation / fraction :-

36 × 1000 m / 3600 s = 10 m/s

So correct answer is (a) 10 m/s
