Answer:


Step-by-step explanation:

Length of train is 250 m.

Speed of train is 90km/h;

Now converting the unit of speed in to m/sec

So it is 90*1000/3600=25m/sec.

A. Train is 25m far in one sec.

B. As the formula of, Velocity=\frac{Distance}{Time};

Time=\frac{250}{25};

Time= 10Sec.

C. Again we are using the formula of time=\frac{Distance}{Time};

Here total distance is= Train length+Length of platform;

Total Distance=225+250=475m;

Time=\frac{475}{25}=19 Sec.
