if it takes 40 seconds to walk 50 steps. how long does it take to take 10,000 steps?

Given:
It takes 40 seconds to walk 50 steps
We will find, how long does it take to take 10,000 steps
Let it takes x seconds
So, using the ratio and proportion:
Seconds : Steps
40 : 50
x : 10,000
Using the cross product, we will find the value of (x) as follows:
[tex]\begin{gathered} 50x=40\cdot10,000 \\ \\ x=\frac{40\cdot10,000}{50}=8,000 \end{gathered}[/tex]So, x = 8,000 seconds
So, the answer will be 8,000 seconds
