Exam Success Strategies

  • Check your units: Always write the correct units with your answer
  • Convert first: Get all measurements in the same units before calculating
  • Use formula triangles: Draw them if you get stuck - cover what you want to find
  • Average speed ≠ average of speeds: Always use total distance ÷ total time
  • Show clear working: Even for simple calculations, show your method
  • Reasonableness check: Does your answer make sense? A car speed of 200 m/s is clearly wrong!

Convert 72 km/h to m/s
Divide by 3.6 72 ÷ 3.6 = 20 m/s Check: 72 km/h means 72000 m per 3600 s 72000 ÷ 3600 = 20 m/s
Convert 25 m/s to km/h
Multiply by 3.6 25 × 3.6 = 90 km/h Check: 25 m/s means 25 metres per second 25 × 3600 ÷ 1000 = 90 km/h
