Answer:

B. Jordin's distance was longer by 20 meters.

Explanation:

The distance Samantha runs = Samantha's speed ×  Samantha's time = 10 m/s × 10 s = 100 m

The distance Jordin runs = Jordin's speed × Jordin's time = 8 m/s × 15 s = 120 m.

The difference in the distance run = (120 - 100) m = 20 m.

So, Jordin's distance is 20 m more than that of Samantha.

So, Jordin's distance was longer by 20 meters is the answer.
