Question

Pls help I don't get the answer

Answer 1

0.5

Explanation:

We have the formula

`(n)/(p) = 140`

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.
