Answer:
Josh won the race 5 seconds ahead of Rafael
Explanation:
The winner of the race is the individual who completes the race in the shortest time. From the graph, Josh reaches the finish line at the 15 seconds mark while Rafael finishes at the 20 seconds mark.
The difference in the time is thus;
20 - 15 = 5 seconds.
Therefore, Josh won the race 5 seconds ahead of Rafael
