Answer:
1. 400/20 = 20
2. 50/10= 5
3. 90/45 = 2
4. 395,000/9000=43.8
5. 16/0.25 = 64
Step-by-step explanation:
Speed= distance divided by time.
1. 400 m (distance) ÷ 20 seconds (time)
2. 50 meters (distance) ÷ 10 seconds (time)
3. 90 m (distance)÷ 45 seconds (time)
4. 395,000 m (distance) ÷ 9000 seconds (time)
5. 16 km (distance)÷ 0.25 hours ( time)
