Answer First: Distance = 100m...
Displacement = 10m and 10√2m based on Raju's position!
To know about 2 Displacement and Raju, read further!
Well, let's Recall:
Person's name is Azlaan, let's say he is Raju!
Side of Square track=10m
Time taken to complete one round=40s
Hmmm, it's solved
As In 2 minutes and 20 second that I 140s he will complete 2 round and will be half a distance to complete 3rd one...
So he has completed 2(4×10m) + 2(10m) distance that is 100m..
And as far as Displacement is concerned, it's depends if Raju is standing at a corner or a side for side it's will 10m(Shortest Distance) and for corner (10√2m)!
Enjoy!
