Question

The pacelength p is the distance between the rear of two consecutive footprints. for men, the formula, n/p = 180 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 120 cm. the formula applies to bernard's walking. calculate bernard's walking speed kmph.

Answer 1

n/P = 144

n = 144 * P

P = 1.64

n = 144 * 1.64 = 236.16 approx 236 steps per minute we are taking n in integer for it represents no. of steps

now v = d / t

v = 1.64 * 236 meter/minute

v = 387.04 meter / minute

or v = (387.04/1000)/(1/60)

or v = 387.04*60/1000 = 23.2224
