Answer 2

Answer:

a)25 m/sec

Step-by-step explanation:

First, you have to convert Kmph(Km/hr) unit into mps(m/s).

1 Km = 1000 m,

1 Hour = 60 Minutes = 60 * 60 Seconds i.e. 3600 Seconds

So, 1 Km/hr = 1000/3600 m/s

= 5/18 m/s

Now,

90 km/hr = 5/18 * 90 m/s

= 25 m/s

Train is moving at the speed of 25 m/s.
