Make a data of any five trains starting from Delhi and going to different states (any five) in
India.
(a) Distance covered.
(b) Displacement (you can make use of Atlas to find displacement.)
(c) Average time taken to reach the destination
(d) and hence find the average speed of each train.

Disclaimer: This question seems a bit ambiguous and incomplete.
Concept:
Displacement is the linear distance between two points in space.
Average Speed = Distance Travelled/ Time Taken
Given:
The starting point of the trains in Delhi and the data of the 5 cities (destination) are as follows:
____________________________________________________
Destination Distance(km) Displacement(km) Time (hr)
Jaipur 235 264 5.24
Indore 670 824 15.40
Ludhiana 280 312 5
Lucknow 418 475 8
Kolkata 1300 1453 17
____________________________________________________
To Find: Average Speed
Solution:
Avg. Speed Jaipur: 264/5.24= 50.38 kmph
Avg. Speed Indore: 824/15.40= 53.50 kmph
Avg. Speed Ludhiana: 312/5= 62.4 kmph
Avg. Speed Lucknow: 475/8=59.37 kmph
Avg. Speed Kolkata: 1453/17= 85.47 kmph
Hence we have calculated the average speed of all the trains. If we had to calculate average velocity we would have used displacement instead of distance.
