It seems that at 24 frames per second, 35mm film runs at about 90 feet per minute ... landing you at about 1350 feet.
The two balloons are 150-10 = 140 metres apart. They are travelling towards each other at a speed of 15+20 = 35 metres per minute. 140 m at 35 m/minute takes 140/35 = 4 minutes.

There is no difference at all if the balloon is not inflated or inflated with air.
Brian Jones (UK) and Bertrand Piccard (SUI) successfully circumnavigated the globe in the Breitling Orbiter, a Roziere balloon, landing in Egypt March 21st, 1999 after 19 days, 21 hours, and 55 minutes in flight. This was the first circumnavigation flight by a balloon.
I presume you mean without an airborne heater. The answer is, there is no fixed time! It could range from a few minutes to the best part of a day. It all depends on the rate the balloon loses heat, which in turn depends on the size of the balloon, the weight of the balloon, the insulation and porosity properties of the balloon fabric, and the amount of solar heating, if any, that it receives.

The highest human altitude in a balloon was 113,740 feet (34.67 km). Malcolm_Ross and Victor A. Prather reach this altitude on May 4, 1961. This record is unbeaten until October 14, 2012 when Felix Baumgartner jumped from about 120'000 feet
The first hot air balloon, created by the Montgolfier brothers in 1783, carried a sheep, a duck, and a rooster as passengers. The flight lasted for about 8 minutes, reaching an altitude of about 1,500 feet.
The time it takes for a balloon filled with hot water to pop can vary depending on factors such as the temperature of the water, the material and thickness of the balloon, and the surrounding environment. Generally, a balloon filled with hot water can pop within a few seconds to a few minutes as the heat weakens the structure of the balloon.
On the 19th September 1783 Pilatre de Rozier launched the first hot air balloon. The passengers were a sheep, a duck and a rooster. The balloon stayed in the air for 15 minutes and then crashed to the ground. Two months later the Montgolfier brothers launched a balloon from the centre of Paris which flew for a period of 20 minutes

The first successful hot air balloon ascent in the United States took place on September 22, 1783. This event was conducted by a Frenchman, Jacques Alexandre Charles, in front of an audience in Philadelphia. The flight lasted approximately 45 minutes and reached an altitude of about 3,200 feet. This marked a significant milestone in the history of aviation in the U.S.
