Explanation:

Speed=distance/time

15/3 meters per second

5 meters per second

17)

100 kilometers=100,000 meters

1 hour=3,600 seconds

100,000/3,600=27.7777 (7 repeating)

About 27.78 meters per second

18)

9 minutes=540 seconds

540+12=552 seconds

2,000/552≈3.62 meters per second

19)

100 kilometers=100,000 meters

45 minutes=2,700 seconds

100,000/2,700=37.037037037 (037 repeating)

About 37.04 meters per second

5k=5,000 meters

20 minutes=1,200 seconds

1,200+36=1,236 seconds

5,000/1,236≈4.05 meters per second
