Jon's running rate is $\dfrac{1}{3}$ kilometers per minute.
Increase in Distance ran = $6-3=3$ km Time duration = $9$ minutes The running rate can be computed by dividing the increase in distance ran by the time: Running Rate = $\dfrac{3\text{ km}}{9\text{ minutes}}=\dfrac{1}{3}$ kilometers per minute.
