a lady bug walks 10 cm forward then 5 cm backwards in 20 seconds what is the average speed of the ladybug class=

Respuesta :

A lady bug moves 10 cm forward and 5 cm backwards

so total distance moved by lady bug = 10 + 5 = 15 cm

total time taken by the lady bug

t =  20 s

so the average speed is given as

[tex]v = \frac{d}{t}[/tex]

[tex]v = \frac{15}{20}[/tex]

[tex] v = 0.75 cm/s[/tex]

so its average speed is 0.75 cm/s
