*UPDATE* Ned has 19k Health and gives 1250 xp NON-RESTED per kill to a level 70. Lunchbox has 9k health and gives 1k xp to a 70. Ned will respawn riding lunchbox 20 seconds after LUNCHBOX dies, not after Ned dies.
As I'm sure everyone knows, the npc Nedar, Lord of Rhinos - NPC - World of Warcraft is a relatively easy mob to kill. He is for the quest Ned, Lord of Rhinos... - Quest - World of Warcraft and can be soloed by all classes. Well as of the latest patch, he is currently on a nearly-instant respawn rate. By the time I killed his mount and had him to about 50%, a second version of him would spawn. I think the reason for this is because the respawn triggers when Lunchbox dies, which is his mount.
Here is a pic with proof and the coords for his spawn point. It's a 20 second timer after Lunchbox dies (Borean Tundra 48, 40):
