2 min 20 sec  = 140sec

no:of rounds covered in }          140   =  3.5 rounds
                        140sec }           40       

dist travelled  =       2 X 22  X 100 X 35 
                                   7                10 
                          = 44 X 10 X 5       
                          = 440 X 5
                          = 2200 msq
displacement  =  200 m 

because when the athelete  covers 3.5 rounds he will come on the opp side of the starting point and the diametre is 200 m. So the displacement is 200....
