From x = 1.0 m to x = 4.25 m, displacement = 3.25 m
Average velocity of crawling of baby = 0.226 m/s
We know that time taken = Displacement/Time
= [tex]\frac{3.25}{0.226}[/tex]
= 14.38 seconds
So, the baby will take a time of 14.38 seconds from x=1.0m to x=4.25m at an average velocity of 0.226 m/s.
