Answer 2

Answer

• Time taken by the train = 7.04 hours (approx.)

To Find

• Time taken by the train to complete the journey.

Given

• Distance between New Delhi and Lucknow = 507 Km.

• Speed of the train = 72 Km/h.

Step By Step Explanation

Given that the distance between New Delhi and Lucknow = 507 Km. Average speed of the train = 72 Km/h.

We need to find the time taken by the train to complete the journey.

So let's do it !!

Let us consider time be x.

$\red\dag \boxed{ \bf{\green{Speed = \cfrac{Distance}{Time}}}}$

By substituting the values

$: \implies \sf 72 = \cfrac{507}{x} \\ \\ : \implies \sf72x = 507 \\ \\ : \implies \sf \: x = \cancel\cfrac{507}{72} \\ \\ : \implies {\bf {x = 7.04 \: hours}} \: { \sf{(approx.)}}$

Therefore time taken by the train = 7.04 hours (approx.)
