Speed = (distance covered) / (time to cover the distance) .

Distance covered = (mark at the end) minus (mark at the beginning)

                             =   (64m - 4m) = 60 meters .

Speed = (60 meters) / (30 seconds)  =  2 meters/second .

We don't care about the bridge or the other two elephants.
They don't have any effect on the question or the answer.
