A:a whale can stay under water for more than a hour. it can stay in water for about 50-80 minutes.
Up to 30 min.

The Sperm whale can hold its breath for up to 90 minutes. See the related link for more information.

It varies between each whale.

Some river-dwelling cetaceans, such as the baiji and the Indus river dolphin, can only hold their breaths for up to five minutes. However, the fin whale can hold its breath for up to twenty minutes, whereas the giant sperm whale can hold its breath for as long as two hours (though the average duration seems to be about forty to ninety minutes). It really does depend on many factors, such as the environment of the whale, how deep it has to dive to hunt, the size of the whale and the age of the whale.

From 20 minutes to 2 hours.

Whale blood holds more oxygen than human blood. Also, taking several deep breaths before it dives adds extra oxygen to a whale's blood. During the dive, the whale draws on this stored up supply of oxygen. When it's gone, the whale returns to the surface to breathe.

Whales do not have especially large lungs, they just make use of the lungs they do have. When we breathe, we fill about one fourth of our lungs with air. When whales breathe in, the air fills almost all of their lungs. Also, whales use up the air in their lungs a lot slower than we do. That's because a whale's heart beat gets slower when it dives; a slow heart beat helps stretch out the supply of air.
