I can help you with the scuba but the way you worded your question, it can be taken two ways.
If you meant to ask how long a typical open water certificate takes to earn ( the scuba course), that can vary from 2 days to whenever you decide to finish it all.
If, on the other hand, you meant to ask how long a single tank of air lasts on a dive, that too varies. It depends on the depth the diver is going to and how much air that diver is inhaling with each breath and if the diver is doing anything strenuous.
The deeper you go, the more air is consumed with each breath because that air has to be delivered to you at the same or slightly higher pressure than the surrounding water happens to be. Deeper = higher water pressure exerted on you and the higher pressure air delivered to you to breathe. Your tank won’t last nearly as long as it would at a shallower depth. The difference could be as much as 40 minutes easily on a 130 foot dive versus a 30 foot or shallower dive
Everyone’s lung capacity is different. Your normal breath may not be the same volume as mine, for example.
Lastly, it’s the same as on the surface. If you’re doing something that requires effort, you breathe a little harder. No different when you dive. Swimming against a current can get you out of breath just like running up a long hill.

Across the world there are lots of places where you can bungee jump. You will find a bungee jumping platform wherever you can find a canyon, bridge, or dam that gives more than a few 100 feet of height. The Bungee Tower in Cairns, the Verzasca Dam in Switzerland and the highest one of all, the Macau Tower in China are some of the most famous bungee jumping points in the world.
and from this site…
AJ Hackett leapt from a platform located 233m high, and rebound at 34m aboveground. The total length of fall is approximately 199m, at a speed of up to 200km/h. The attempt will be listed in the Guinness World Records, surpassing the old record by 19m.
And for scuba, I can go from experience. When using a standard 80 cuft tank, I usually spend from 30 minutes to one hour underwater. If I go deep, say 40 meters, I may only spend 15 minutes underwater.
There is a relationship between depth underwater, and how much time you can spend. It gets complicated if you are doing multiple dives on the same day. It has to do with pressure and dissolved nitrogen in your blood.
