The pacelength P is the distance between the rear of two consecutive footprints. For men, the formula, n/P = 144 gives an 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 gives an approximate relationship between n and P where, n = number of steps per minute and P = pacelength in meters. Bernard knows his pacelength is 164cm.
  Number of steps in one minute = 144*1.64
  Distance travelled in 1 minute = 144*1.64*1.64 mtrs
  Distance travelled in one hr = 144*1.64*1.64*60/1000 km = 23.24 km approx
