Hi

We know that average velocity is given by

= net displacement total time

Now,
net displacement = final position - intial position
= (13i + 14j) - (2i +3j)
= (13i - 2i) + (14j - 3j)
= 11i + 11j

average velocity = (11 i + 11j)/5

Then the magnitude of average velocity
= (121/25+ 121/25 ) ^1/2

= 11(2/5 )^1/2

Thankyou
