Average Speed

Understanding the concept of average speed

Before you learn....

Multiple Choice

Formula of getting the average speed

• $$\frac{Total\ dis\tan ce\ travelled}{Total\ time\ taken}=Average\ Speed$$

• Distance / Speed = Time

Tree A and Tree B are 9 m apart. Tree B and Tree C are 21 m apart. Shaun ran from Tree A to Tree B in 2 s. THen he ran from Tree B to Tree C in 3 s. FInd Shaun's Average speed for the distance from Tree A to C.

Total distance from Tree A to Tree C = 9 + 21 = 30 m

Total time taken to run from Tree A to Tree C - 2 + 3 = 5 s

Average Speed = 30 / 5 = 6 m/s
