The two frogs wanted to switch positions on the two lotus leaves, and they jumped up at the same time at the same command, but the two plops failed, and the two frogs collided and fell into the water. The falling water point is 1 meter away from the midpoint of the distance between the two lotus leaves. So, what is the difference in distance between the two frogs?
