The 20 questions

  1. What is the formula for average speed?

    • Speed = distance + time
    • Speed = distance × time
    • Speed = time ÷ distance
    • Speed = distance ÷ time

  2. Which unit is commonly used to measure the speed of a car on a road?

    • Kilometres per hour (km/h)
    • Kilograms (kg), which is the unit used to measure how heavy a car is
    • Seconds (s), which is the unit used to measure how long a journey takes
    • Newtons (N), which is the unit used to measure a push or a pull

  3. A cyclist travels 36 km in 2 hours. What is the average speed?

    • 34 km/h
    • 72 km/h
    • 18 km/h
    • 38 km/h

  4. A runner covers 100 m in 12.5 s. What is the average speed?

    • 12.5 m/s
    • 0.125 m/s
    • 1250 m/s
    • 8 m/s

  5. A car travels 150 km at an average speed of 60 km/h. How long does the journey take?

    • 2.5 hours
    • 90 hours
    • 0.4 hours
    • 9000 hours

  6. A runner covers 120 m in 30 s, then 60 m in 10 s. What is the average speed for the whole run?

    • 6 m/s
    • 4 m/s
    • 4.5 m/s
    • 5 m/s

  7. Which is the correct conversion of 5 m/s into km/h?

    • 18 km/h
    • 50 km/h
    • 0.005 km/h
    • 5 km/h

  8. Why is the average speed of a whole journey often lower than the highest speed reached?

    • Because the highest speed is only measured at the start
    • Because speed is always measured in the wrong unit
    • Because distance is always larger than time
    • Because the journey includes slower parts and stops

  9. A bus travels at 20 m/s for 30 s. How far does it go?

    • 600 m
    • 60 m
    • 50 m
    • 0.67 m

  10. A train covers 240 km in 3 hours. What is its average speed?

    • 80 km/h
    • 70 km/h
    • 243 km/h
    • 720 km/h

  11. Which formula gives the time taken for a journey?

    • Time = speed − distance
    • Time = distance ÷ speed
    • Time = speed ÷ distance
    • Time = distance × speed

  12. A person walks at 1.5 m/s for 4 minutes. How far do they walk?

    • 1440 m
    • 6 m
    • 360 m
    • 90 m

  13. Which of these is the fastest?

    • 80 km/h
    • 25 m/s
    • 1000 cm/s
    • 20 m/s

  14. A sprinter's average speed over 200 m is 8 m/s. How long does the race take?

    • 208 s
    • 0.04 s
    • 1600 s
    • 25 s

  15. A ship travels 50 km in 2.5 hours, then 30 km in 1 hour. What is its average speed for the whole trip?

    • 40 km/h
    • 22.9 km/h
    • 20 km/h
    • 25 km/h

  16. A car travels 90 km in 1.5 hours. What is its average speed in m/s?

    • 135 m/s
    • 60 m/s
    • 16.7 m/s
    • 1.7 m/s

  17. A 500 m race is run at a steady 5 m/s. How long does it take?

    • 10 s
    • 2500 s
    • 100 s
    • 0.01 s

  18. Which information do you need to calculate the distance travelled?

    • Time and temperature
    • Mass and speed
    • Speed and time
    • Force and mass

  19. A car travels 300 m in 15 s, then stays still for 5 s. What is its average speed over the 20 s?

    • 300 m/s
    • 15 m/s
    • 20 m/s
    • 60 m/s

  20. A snail moves 3 m in 60 s. What is its average speed?

    • 0.2 m/s
    • 180 m/s
    • 0.05 m/s
