Somebody put an explosive device in a watermelon.  Soon after the explosion, some pictures were taken.  The pictures show two halves of the watermelon moving in opposite directions.  In the pictures, the two watermelon halves are about 20m apart, and they are moving away from each other at a rate of approximately 10m/s.  Approximately how long after the explosion was the picture taken?
