Mercedes can walk 0.083913 km per minute


y\text{ = 0.083913x}

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;


\begin{gathered} (y)/(x) \\ \\ \end{gathered}

So, we proceed to divide the number of kilometers walked by the number of minutes

The proportion in this case will be;


(1.93)/(23)\text{ = 0.083913 }

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;


y\text{ = 0.083913x}
