Mercedes can walk 0.083913 km per minute
[tex]y\text{ = 0.083913x}[/tex]
Here, we want to write a proportion and solve it
We want to get the number of kilometers y that mercedes can walk in x minutes
To get the value of y, we simply solve the proportion
Mathematically, the proportion would be;
[tex]\begin{gathered} \frac{y}{x} \\ \\ \end{gathered}[/tex]So, we proceed to divide the number of kilometers walked by the number of minutes
The proportion in this case will be;
[tex]\frac{1.93}{23}\text{ = 0.083913 }[/tex]So, what this means is that she can walk 0.083913 kilometers in a minutes
So if she walks 0.083913 kilometers in a minute, then, the number of kilometers y, walked in x minutes will be;
[tex]y\text{ = 0.083913x}[/tex]
