A person runs 15 kilometers in two hours what is his/her average speed ​
bazaltina [42]

Answer:

\displaystyle V=7.5\ km/h

Explanation:

<u>Average Speed </u>

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:

\displaystyle V=\frac{d}{t}

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

\displaystyle V=\frac{15\ km}{2\ h}

Calculating:

\boxed{\displaystyle V=7.5\ km/h}
