Total distance travelled by the object is

And,net displacement of the object is

negative sign means direction of displacement is towards North.

Now,average speed =Total distance covered/total time taken=

And,average velocity =Total displacement/Total time taken

**Remember average speed is a scalar quantity wheras average velocity is a vector quantity**
