Answer:
0.5
Explanation:
We have the formula
![(n)/(p) = 140](https://img.qammunity.org/2023/formulas/mathematics/college/7f1ks0ylexe4hwh3kdqoyfmsxchie4uzro.png)
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.
