stand in front of a wall with a watch and say something now record the time when you heard an echo and also measure the distance between you and the wall now you know the distance and time. you can determine the speed.

To hear an echo , sound has to travel a distance from the reflector and then back to the source so, if distance between source and reflector is x, then total distance travelled by sound will be 2x.
Hope this will help you.........
