Let’s solve each problem one by one. We’ll use the formula:
Speed = Distance ÷ Time
We’ll make sure units match (like miles and hours, or meters and seconds) before dividing.

Problem 1:
A dog runs 200 meters in 4 seconds. What is its speed?
→ Speed = 200 meters ÷ 4 seconds =
50 meters per second
---
Problem 2:
A car travels 300 miles in 6 hours. What is its average speed?
→ Speed = 300 miles ÷ 6 hours =
50 miles per hour
---
Problem 3:
A cyclist rides 75 kilometers in 3 hours. What is her average speed?
→ Speed = 75 km ÷ 3 hours =
25 kilometers per hour
---
Problem 4:
An airplane flies 1800 miles in 4 hours. What is its average speed?
→ Speed = 1800 miles ÷ 4 hours =
450 miles per hour
---
Problem 5:
A runner completes a 400-meter race in 50 seconds. What is his speed?
→ Speed = 400 meters ÷ 50 seconds =
8 meters per second
---
Problem 6:
A train goes 600 kilometers in 5 hours. What is its average speed?
→ Speed = 600 km ÷ 5 hours =
120 kilometers per hour
---
Final Answer:
1. 50 m/s
2. 50 mph
3. 25 km/h
4. 450 mph
5. 8 m/s
6. 120 km/h
