How do you calculate speed?

• Distance ÷ time

• Distance x time

• Time ÷ distance

How do you calculate distance?

• speed ÷ time

• speed x time

• time ÷ speed

How do you calculate time?

• Distance x speed

• speed ÷ distance

• Distance ÷ speed

Acceleration is defined as......

• an object maintaining speed

• the rate of change of speed

• speed x time
