5 step forward and 3 step backwards ,net displacement is 2m and take 8s Similarly for next steps ,total time taken 16s and 4m Same procedure for others up to 8m net displacement and take 32 s But afterwards ,when he walks 5 step forward he drop into pit . Because the distance from starting is 13m So...
