EXPLANATION:
The proportion states that he walks 1.93 kilometers at a constant speed in 23 minutes, so we can formulate the equation in the same way:
-First we must divide to find the constant or the proportion, then we divide 1.93 by 23; we represent the constant with the letter k:
[tex]\begin{gathered} K=\frac{y}{x} \\ k=\frac{1.93}{23} \\ k=0.08 \\ \text{ANSWER:} \\ \text{The constant or porportion is :0.083} \end{gathered}[/tex]With the constant found we can propose an equation that determines the constant speed at which Halona walks at any time.
Now we can formulate the following equation:
[tex]\begin{gathered} y=(z)(k) \\ y=(z)(0.08) \\ where\text{ z is }any\text{ moment of time; an k is the }cons\tan t\text{ value} \end{gathered}[/tex]Multiplying any time with the constant will give us the constant speed.
IMPORTANT NOTE:
When we give different values to time, it must be multiplied by the constant, which means that the speed remains stable.
