The pacelength P is the distance between the rear of two consecutive footprints. For nen, the formula, n/P = 113 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 106 cms. The formula applies to Bernard's walking. Canculate Bernard's walking speed in KMPH.

• n/P = 113
  no of steps per minute = 113 P = 113 *1.06 steps
  Distance travelled per minute = n*P = 113*1.06*1.06 mtrs
  Distance travelled in 1 hr = 60*113*1.06*1.06 mtrs = 60*113*1.06*1.06 /1000 kms = 7.618 kmph

• the ans shd be 7.61....the formula is 113*1.06*1.06*60/1000

• s ofcourse...given is n/p=113.
  and since its n metres..we write the distance travelled per minute = 113 * 1.06 * 1.06 metres.
  so distance travelled in 1 hour is 113 * 1.06 * 1.06 * 60/1000 (1000 is to convert to kmph)
  now u get the ans as 7.16...

• n/p=113
  no of steps per min=113*p=113*1.06=119.78=119(next step not completed)
  distance per min=(n-1)*p=118*1.06 mtrs=125.08mts
  speed=0.12508*60kmph=7.5048kmph

• hey can any body solve this problem .
  first 3 no.s are 1,3,8...so on (fibonacci series) den at whch postion will u get 143?

• 7.618 is thhhhhhheeeee ans
• 12 years agoHelpfull: Yes(0) No(0)
• Ans: 7.632km/h
  Explanation:
  P=1.06 meter
  n=113*1.06=119.78=120steps(round off to nearest integer)
  distance covered in 1 minute is=n*P=127.2 meters per minute = 127.2*60/1000km/h= 7.632km/h
