Answer 1

Answer :-

• Average speed of the train = 63.33 Km/h

To Find :-

• Average speed of the train.

Given :-

• A train runs from New Delhi to Kolkata covering a distance of 400 km in 7 hours.

• Then it covers a distance of 550 km in 8 hours.

Step By Step Solution :-

In this question we already know the distances and the time .

So let's find out the average speed !!

As we know ⤵

$\boxed{ \underline{ \sf{ \purple{Average\:Speed= \dfrac{Total \: Distance}{Total \: Time \: Taken}}}}}$

So by substituting the values ⤵

$\implies \sf \cfrac{400 + 550}{7 + 8} \\ \\ \implies \sf \cancel\cfrac{950}{15} \\ \\ \implies \sf63.33$

So average speed of the train = 63.33 Km/h
