Steps

1. Create a "miles" variable

Go to the "variables" blocks and click "Make a variable." Call this one "miles." 

2. Set miles to 0 at the start of the game

In your car's code, grab another "when green flag clicked" block and put it anywhere. Add a "variables" block called "set __ to __" and set miles to 0. 

3. Raise miles by speed forever

Use a forever loop, and the "change __ by ___" variables block. There are many ways to do this, so try experimenting on your own.
