Question

The picture shows the footprints of a man walking. The pacelength P is the distance

between the rear of two consecutive footprints.

For men, the formula, =140

P

n , gives an approximate relationship between n and P

where,

n = number of steps per minute, and

P = pacelength in metres.


Question 1:

Answer 2

Answer:

Question 1: P = 1/2 or 0.5

Step-by-step explanation:

Question 1.

n/P = 140

70/P = 140 - Replacing n with 70 because n is the number of steps per minute

So we have to find P.

70 = 140P - Multiplying P on both sides

70/140 = P

P = 1/2 - So P equals to 0.5 or 1/2
