Answer 1

$\huge{\pink{\bold{\boxed{\ulcorner{\star\:Answer\: \star}\urcorner}}}}$

✧ Speed $= 36.25 \frac{Km}{hr}$

Explanation:

Distance between Mumbai and Indore = 725 kms.

Time taken = from 8 pm to 5 pm of next day =21 hrs

But train halts for an hour,  

So Net time taken by train to cover  $= 21 - 1 = 20$ hrs  

⇒ $Speed = \frac{Distance}{\textrm{Time taken}}$

⇒ $Speed = \frac{725}{20}$

⇒ Speed $= 36.25$ Km/hr.
