The running time of Beast of War: Armoured Command is 10 minutes longer than that of Alpha Epsilon, which is 30 minutes shorter than that of Millennium. If Millennium runs for 2 hours, what is the running time of Beast of War: Armoured Command in minutes? Let's be accurate as possible.
One hour contains 60 minutes so 2 hours contain 60 * 2 = 120 minutes. Alpha Epsilon's running time is 30 minutes less than that of Millennium (which runs for 120 minutes) hence 120 - 30 = 90 minutes. Beast of War: Armoured Command runs for 10 minutes more than Alpha Epsilon hence 90 + 10 = 100 minutes.
The answer: 100.
