KSSM Form 2 : Speed and Average Speed

What two measurements are needed to calculate average speed?

• Distance and Time

• Volume and Mass

• Mass and Time

• Speed and Distance

What is the formula for average speed?

• Average Speed = Total Time $\div$ Total Distance

• Average Speed = Total Time + Total Distance

• Average Speed = Total Distance $\div$ Total Time

• Average Speed = Total Distance $\times$ Total Time
