Answer:
0.5
Step-by-step explanation:
We have the formula
[tex] \frac{n}{p} = 140[/tex]
N is the number of steps per minute, and we know that Heiko takes 70 steps per minute, making N 70. Now we can reverse this simple formula - if n over p is 140, then 140 X P gives us N. Or, in other words, 70 divided by something is 140. 70 divided by a half is 140, making P 0.5.
