Different between the Distance and Displacement

Many student little bit confuse about Distance and Displacement

Let us see define first
Distance- it is total path covered by any body to reach from one point to an other
Distance is a scalar quantity 

Displacement- it is the shortest distance that a body take reach the from one point to another
displacement is a vector quantity 

one question could be raised that
Is distance and Displacement can be equal

a) yes
b) no

Answer - No

because distance is a scaler quantity and displacement is vector quantity 
If we talk about Magnitude only than we can say both may be Equal
