Answer:
The answer is average speed is equal to 0.25cm/sec
Step by step Explanation:
1-The average speed is defined as the relationship between the displacement that a body made and the total time it took to perform it.
2- The formula that allows to calculate the average velocity is [tex]V = \frac{ΔX}{ΔT}[/tex] where (V) is the average speed, (ΔX) is the displacement and (ΔT) is the time interval.
3- As the ladybug advanced 10cm and moved back 5cm we have that the displacement is equal to 5cm, and the time interval is equal to 20 sec.
4- having this we can replace the problem data and find the average speed.
[tex]v = \frac{5cm}{20sec} \\v = 0.25\frac{cm}{sec}[/tex]
