Answer:
Yes… first make him to stand exactly 1 km (or any distance more than 100m ,use tape ) away from explosion. And ask him to start the stopwatch whenever the flash appear and stop when he heard the sound.
Now this is the time taken by the sound to travel a km .
Speed= distance / time
Here we get it in m /sec
