Final answer:
The second girl ran 0.59 seconds faster than the first girl, as calculated by the difference in their finishing times.
Step-by-step explanation:
The first girl ran the 100-meter dash in 14.47 seconds, and the second girl ran it in 13.88 seconds. To find out how much faster the second girl ran, we need to calculate the difference in time between the two. By subtracting the time of the second girl from the time of the first girl, we get:
14.47 seconds - 13.88 seconds = 0.59 seconds.
Therefore, the second girl ran 0.59 seconds faster than the first girl.
