Question

A train whose length is 150 m, passes a telegraph pole in 10 sec. Find the speed of the train in km/hr.

Answer 1

Answer:

see, first of all

Speed=Distance/Time

SI unit of speed is Km/Hr

But over here the units are in m/s

So,we to change it into Km/Hr

150m will change into 150/1000Km and 10s into 10/60 hrs

Speed=150/1000km which will wholly be divided by 10/60 hrs

The answer will be 0.9 Km/hr
