Question

A train 200 m long running with the speed of
60 km/hr passes a man who is running at 12
km/hr in the same direction of the train. How
much time will it take to cross him?​

Answer 1

Step-by-step explanation:

For answering these types of questions just consider 2–3 points

Firstly to cross the pole train has to cover its whole length

So total distance covered = length of the train

Second point is you have to see the units are same or not

Here distance is in meter and speed is in km/hr and you have to find time in sec.

So for that make all the units same.

Speed of train = 60km/hr

= 60*(5/18) simple way of changing km/hr to m/sec

Now the formula

Speed = distance / time

60*(5/18) = 200/time

300/18 = 200/time

time = 200*18/300

time =12 sec

Train will cross pole in 12 sec.
