Question

A train from station a to b covers the distance of 616 km

Answer 1

Given :

★  Distance between Station A and Station B : 616 km

★  Train travels with a Uniform speed : 112 kmph

$\bigstar\;\;\textsf{We know that : \large\boxed{\mathsf{Speed = \dfrac{Distance\;traveled}{Time\;taken}}}}$

$\implies \mathsf{112 = \dfrac{616}{Time\;taken}}$

$\implies \mathsf{Time\;taken = \dfrac{616}{112}}$

$\implies \mathsf{Time\;taken = 5.5}$

☯  Time taken to travel from Station A to Station B is 5.5 hours

As the train travels with uniform speed and the distance between Station A and Station B is same as the distance between Station B and Station A, It takes same time to return from Station B to Station A

☯  Time taken to travel from Station B to Station A is 5.5 hours

Given : Train halts at Station B for one hour before starting back

It means : Time taken by the train to complete the entire journey and reach back to Station A will be : Sum of time taken to travel from Station A to Station B and Halting time at Station B and time taken by the train to travel from Station B to Station A

$\implies \textsf{Complete train journey time = (5.5 + 1 + 5.5)\;hours}$

$\textbf{Answer :}\;\textsf{Complete train journey time = \large\boxed{\textsf{12\;hours}}}$
