Answer:

[tex]\displaystyle V=7.5\ km/h[/tex]

Explanation:

Average Speed

If an object travels a distance d in a time t regardless of the direction, the average speed is the quotient of the distance over the time:

[tex]\displaystyle V=\frac{d}{t}[/tex]

It's known a person runs d=15 kilometers in t=2 hours, thus his/her average speed is:

[tex]\displaystyle V=\frac{15\ km}{2\ h}[/tex]

Calculating:

[tex]\boxed{\displaystyle V=7.5\ km/h}[/tex]
