Answer 2

Here your answer goes  

Step :-1  

Convert km into m  

186 km = 186000 m

Convert time into second

2 hours 35 minutes = 9300 second

Step :- 2

We know that ,

Speed =$\frac{Distance}{Time}$

$\frac{186000}{9300}$

20m/s

Step :- 3

Convert  into km/hr

20 *$\frac{18}{5}$

⇒ 72 km/hr

Therefore , the speed of the train is 72 km/hr
