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.
It will have descended 3000 ft.
I would say that depends on the size of the balloon, the gas used to fill the balloon and the atmospheric pressure. Based on these parameters, a balloon may take anywhere from a few minutes to few hours to deflate.
depends on your altitude
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 SRBs are jettisoned from the shuttle system at 2 minutes and an altitude of about 146,000 feet (44.5 km).

If you hold the balloon over the paper for several minutes, nothing significant will happen. The balloon will continue to hold its shape, and the paper will not be affected by it. The only change you may observe is a slight static charge buildup on the balloon, which could potentially cause lightweight objects like the paper to be attracted to it.
