Answer 1

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.
