Answer 2

The speed of the train is 25 m/s.

Step-by-step explanation:

The distance covered by a train, d = 405 km

Time, t = 4 hours 30 minutes = 16200 s

The speed of the train is given by distance covered divided by time. So,

$v=\dfrac{d}{t}\\\\v=\dfrac{405\times 10^3\ m}{16200\ s}\\\\v = 25\ m/s$

So, the speed of the train is 25 m/s.
