Compute km per second for each:

- 10 km in 97 s → 10/97 ≈ 0.10309 km/s
- 8 km in 83 s → 8/83 ≈ 0.09639 km/s
- 18 km in 198 s → 18/198 = 1/11 ≈ 0.09091 km/s
- 15 km in 168 s → 15/168 = 5/56 ≈ 0.08929 km/s

From fastest to slowest (by km/s):
1. 10 km in 97 s
2. 8 km in 83 s
3. 18 km in 198 s
4. 15 km in 168 s
