Paul the penguin's velocity is 3.33[tex]ms^{-1}[/tex].
Explanation:
Paul glided (displaced) 40 meters towards north.
The time he taken to displace is 12 seconds.
∴displacement d= 40m.
time t= 12s.
The speed of a body in a certain direction is the measure of Velocity.
The velocity of the an moving object is given by ratio of the rate of change in the distance by the time taken.
⇒Velocity v= [tex]\frac{displacement}{time}[/tex].
=[tex]\frac{40}{12}[/tex].
=3.33 [tex]ms{-1}[/tex].
Thus the velocity of the Paul the penguin glided on ice is 3.33 [tex]ms{-1}[/tex].
