Answer:
[tex]\frac{4}{10}=0.4[/tex] kilometers per hour.
Step-by-step explanation:
We have been given an [tex]y=\frac{4}{10}x[/tex], which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.
We can see that van travel [tex]\frac{4}{10}x[/tex] kilometers in x hours. To find the constant speed of van, we will substitute [tex]x=1[/tex] in our given equation as:
[tex]y=\frac{4}{10}(1)[/tex]
[tex]y=\frac{4}{10}[/tex]
Since van travels [tex]\frac{4}{10}[/tex] kilometers in one hour, therefore, constant speed of van is [tex]\frac{4}{10}[/tex] kilometer per hour or [tex]0.4[/tex] kilometers per hour.
