D.35(8/11) kmph

✔Let the speed of the train be x km per hour.


Man is walking in same direction, so,


Relative speed becomes = (x-3) km/h.


In 33 secs train travels its own distance i.e. 300m.


Speed of train = 300*18/33*5 km/hour;


Or, x-3 = 32.72 km/h;


Or, x = (32.72)+3


Or, x= 35.72 km/h.

Thanks ✌✌✌
