Grade 9 Speed Calculations Worksheet

Grade 9 Speed Calculations

Read each question carefully and show all your work. Remember the formula: Speed = Distance / Time.

1. A car travels a distance of 240 kilometers in 3 hours. What is its average speed in km/h?

2. A cyclist maintains an average speed of 25 km/h for 4 hours. How far did the cyclist travel?

3. A runner completes a 100-meter race at an average speed of 10 m/s. How long did it take the runner to finish the race?

1. To convert meters per second (m/s) to kilometers per hour (km/h), you multiply by  .

2. To convert kilometers per hour (km/h) to meters per second (m/s), you divide by  .

1. Which of the following units is typically used to measure speed?

2. If you travel 180 km in 2 hours, what is your average speed?

1. Speed is a scalar quantity, meaning it only has magnitude and no direction.

2. Velocity is the same as speed, just with a different unit.

1. A train travels at an average speed of 80 km/h. How long will it take to cover a distance of 400 km? Express your answer in hours and minutes.

2. A person walks 500 meters in 5 minutes. Calculate their speed in meters per second (m/s).

3. An airplane flies at a speed of 900 km/h. How much distance does it cover in 30 minutes?
