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 164cm. The formula applies to Bernard's walking. Calculate Bernard's walking speed in kmph.

• n/p=144
  as bernard knows his pacelength is=164cm
  No. of steps in one min=144*1.64
  dis. travelled in 1 min=144*1.64*1.64cm
  dis, travelled in one hour=144*1.64*1.64*(60/1000)
  =23.62
