Question
Nina’s run:Ryan's run:Time (sec)Distance (m)44 3535 66 47.547.5 88 6060 Nina and Ryan each ran at a constant speed for a 100-meter race. Nina's distance is displayed on the graph, and Ryan's distance for the same section of the race is displayed in the table. Who had a head start, and how big was the head start? had a head start meters.
Solution
To determine who had a head start in the race, we need to compare the distance each runner had covered at the same time.
Looking at the time of 4 seconds, we can see that Nina had run 35 meters while Ryan had run 44 meters.
Therefore, Ryan had a head start.
To find out how big the head start was, we subtract the distance Nina ran from the distance Ryan ran at the same time.
So, 44 meters (Ryan's distance) - 35 meters (Nina's distance) = 9 meters.
Ryan had a head start of 9 meters.
