What is the average speed of train between Alwar and Jaipur. My ans is 1.833km/h and my neighbour says that it is 110 km per hour. Which one is correct answer
Dear Student ,
I) The reference point should be at Delhi because all distances and time are measured from there only.
II) Distance betweeen alwar and jaipur = 260-150 = 110km
train starts from alwar at 11:45 as it stops for 15 minutes after reaching alwar at 11:30
Therefore, time taken by the train to reach jaipur from alwar = 12:45 - 11:45 = 1 hour
Average speed of the train =
