The man takes 40 sec to cover ( 4 * 10 ) 40 metres. This shows he covers one metre in one sec.

In 2 min 20 sec (140 sec) , he will cover a distance of  140 metres.

Thus he completes  14040 = 3.5 rounds in 2 min 20 sec.

Hence it is noticed that he will be at the opposite side from where he started.
