The pacelength P is the distance between the rear of two consecutive footprints. For men the formula n/P=144 gives approximate relationship between n and P where, n = number of steps per minute and P = pacelength in meters. Bernard knows his pacelength is 111cm. The formula is applied to Bernard's walking. Calculate Bernard's walking speed in kmph.

• p pacelength in mt...therefore
  pacelength is 1.11m
  n=p*144no. of steps /min
  bt p in mt
  n=1.11*144m/min;
  159.84m/min
  therefore (159.84*60)/1000km/hr=9.588km/hr
