The average speed of the toy car : 0.2 m/s
Further explanation
Given
The motion of a toy car
Required
The average speed
Solution
Average speed = total distance/total amount of time ,
From the graph :
Total distance travelled : 4
Total time : 20 s
The average speed = total distance (d) : total time (s)
The avg speed = 4 : 20
The avg speed = 0.2 m/s
