60km is converted to 60000m and 1 hour to 3600sec, there for 60000/3600 answer to 16.66 and multiple to 9sec and answer is 149.999.
So, here, the full value as 150 metres.

@All.
We know that;
Velocity = Distance/Time.
so we can write,
Distance = Velocity*Time.
= (16.66)*(9) meters [=> 60km/hr convert into meters = 60*5/18. = 16.66 meter/sec.].
= 150 meters. [ANS].
