allochka39001 [22]

After running for 18 minutes, Julissa completes 2 kilometers. If she is running a 10-kilometer race at a constant pace, then she comletes 1 kilometer after running 9 minutes. Now you can find the distance she run after 1 minute. This is \dfrac{1}{9} km.

Let t be the time in minutes. Then k, the number of kilometers, can be found from proportion:

\dfrac{1}{9}\ km - 1 minute

k km - t minutes.

Thus,

\dfrac{\dfrac{1}{9}}{k}=\dfrac{1}{t},\\ \\k=\dfrac{1}{9}\cdot t.

Answer: k=\dfrac{1}{9}\cdot t.
