Keiko now walks around a new track that includes an outer loop and an inner loop. The outer loop has the same structure with two straight sections of equal length and two semicircular ends, with a width of $8$ meters between the inner and the outer edge. The inner loop, only used on special occasions, has a width of $4$ meters. It takes Keiko $48$ seconds longer to walk around the outer loop than around the inner loop. Find Keiko's speed in meters per second.
