Answer:
Juan wins the race
Step-by-step explanation:
<em>The complete question is attached.</em>
<em />
Time is on the horizontal axis.
Distance is on the vertical axis.
If you look first at y-axis (vertical), you will see that both lines (curves) go upto a distance of 4 miles. So, the race is of 4 miles. Both of them finish.
Now,
If you look at the corresponding x-axis value of where each curve ends, you will see:
Antonio finishes at 15 mins
Juan finishes at 13 minutes
So we can successfully say that Juan wins the race since he finishes 2 mins faster than Antonio.
Juan wins the race
