How long does an airplane oxygen mask last?
Your oxygen will last only about 15 minutes. Passenger oxygen masks typically provide enough air to last 12 to 20 minutes. However, this is usually plenty of time for the pilot to get the plane to a safe altitude where masks aren't needed anymore.
Don't have to land just fly at a lower altitude, where there is more oxygen.

Interesting question but terribly worded.

Come on people! Do you really think after seeing the choices that the question refers to the mask itself? How about put your big pants on & deal with your wrong answers!

The question needs work to be more specific.

Come on, people. You all know what he means. Let's not play semantics. Anyway I got it.

Poorly worded question. The oxygen in the tank might be depleted about 15 minutes after the system is activated and left running, but the mask itself presumably will remain in working order for years whether it's used or not.

Way too vague. The mask itself lasts for years while some non-pressurized aircraft have oxygen systems that provide supplimental oxygen for hours.
