Answer 1

➤ Answer

• Time taken by the train to complete the journey = 5 hours.

➤ Given

• Speed of the train = 100 km/h.
• Distance travelled by the train = 500 km.

➤ To Find

• Time taken by the train to complete the journey.

➤ Step By Step Explanation

Given that a train is travelling at a speed of 100 km/h. We need to calculate the time taken by the train to complete the journey of 500 km.

So let's do it !!

➠ Formula Used

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

➠ By substituting the values

$\longmapsto\tt100 = \cfrac{500}{Time} \\ \\\longmapsto\tt 100 \times Time = 500 \\ \\ \longmapsto\tt Time = \cancel\cfrac{500}{100} \\ \\\longmapsto\bf{\red{Time = 5 \: hours}}$

Therefore, Time taken by the train to complete the journey = 5 hours.
