Core Framework
The mechanics of Speed, Distance & Time
SDT Triangle
D on top, S and T on the bottom.
Speed (S)
Speed = Distance ÷ Time
Time (T)
Time = Distance ÷ Speed
Distance (D)
Distance = Speed × Time
Key Facts to Remember
💡
Speed is usually measured in mph, km/h, or m/s.
🔄
Average speed = TOTAL Distance ÷ TOTAL Time.
➕
Do not mix units (convert minutes to hours if speed is in miles/hour).
➖
30 minutes is 0.5 hours, NOT 0.3 hours!
