Question

How much time does a train take to cover a distance of 507 km between New Delhi and Lucknow if average speed of the train is 72 km/h

Answer 1

Given:

Train travels with an average speed of 72 km/hr between New Delhi and Lucknow to cover a distance of 507 km.

To find:

Time taken for the journey.

Calculation:

Distance is a scalar quantity representing the total path length travelled. It only has magnitude and no direction.

Mathematically, it can be calculated from the product of average velocity and the time taken to cover the distance.

$\sf{distance = speed \times time}$

$\sf{ = > 507 = 72 \times time}$

$\sf{ = > time = \dfrac{507}{72} }$

$\sf{ = > time = 7.04 \: hours }$

So, final answer is:

$\boxed{ \large{ \rm{ time\: taken = 7.04 \: hours }}}$
