The relative speed of man is 100-20=80m/min.
The relative speed of shark is 80-20=60m/min.
Distance travelled by shark in 10 min is
60×10=600m
Distance travelled by man in 10 min is
5 min travel +1min rest + 4 min travel
=5×80 + 0 + 4 × 80
=720 m
The man and shark will never meet as the speed of man is more than that of shark even if he takes rest.
