Clear Understanding

To make you more clear of this, we can have the following Differences:

I walked 49 Metres.

I walked 49 Metres West.

The first line, mentions the distance, the second line is similar to the first one, except it mentions the direction.

Now another example,

My speed was 24 Km/hr

My Speed was 24 Km/hr at East.

This is the difference between Scalar and Vector quantity.

A little harder is the Second Idea :)
