I can measure distance from my house to the next state with ________.
I can measure time from my house to the next state with ______.

4. Three Speed Equations The Speed Equation: Speed = Distance
Time
S=D/T used when solving for Speed.
D=S x T used when solving for Distance.
T=D/S used when solving for Time.
All you do is re-arrange the equation to make it easier to solve for each variable.

5. Speed Triangle Just another way to show the speed equation.
