# How do I find average velocity?

##### 1 Answer

You divide total distance by total time.

#### Explanation:

Sometimes you first have to work out separate distances or times and then add them before you can work out the average.

**Example:**

I travel to Amsterdam (which is not my favourite city) to deliver a parcel and I do the 60 km distance at an average speed of 60 km/h (last part of rush hour). After that I speed back to my favourite town at an average of 120 km/h.

My average speed on the whole trip is **NOT** :

The **correct calculation** is as follows:

The trip to A took me 1 hour, the trip back only 1/2 hour.

This may go against your intuition, but remember, I spent much more time driving slow, than I did driving fast.
