Detailed Solution
Download Solution PDFGiven:
The speed of a train including stoppages is 75 kmph.
The speed of a train excluding stoppages is 90 kmph
Formula used:
Speed = distance/time
Calculation:
Since,
The speed of a train is 90 km/hour excluding stoppages
And the speed of the train is 75 km/hour including stoppages.
So, due to stoppage in 1 hour it covers = (90 – 75) km = 15 km less
∴ Time taken by train in stoppage = 15/90 = 1/6 hour = 10 minutes
∴ Option 1 is the correct answer.
