Rx battery pack
You might just as well ask "Why is there air??" :-D Just a joke..
There is no way to tell, or even average out how many flights you can get from a single battery pack.
One day, the air might be calm and you might just want to bore holes in the sky, so you won't use much battery capacity. The next day (or later in the same day when the wind picks up)you could be trying to do aerobatics, and fighting crosswinds at the same time. You'll use 2-3 times the battery capacity or even more.
You can't guess at something like this. The best thing to do is to check batteries before each flight with a voltmeter that puts a load on the pack. When it gets to 4.8V (assuming it's a 4.8V pack), stop flying and recharge.
One word about buying a voltmeter - you will probably have to buy the leads separately, just to make sure that you get something that matches your particular radio.
I hope this helps some...

Rx battery pack
Even with identical aircraft... you can't say for sure how long the battery will last. Differences in how you handle the aircraft will change how long you get.
With a simple .40 size trainer, standard 4 servos, .40 LA engine, flying it at 50% throttle in smooth easy figure 8 pattern around the field, you can get over 1.5 hour of flight time from a 600 mah pack. Start running at full throttle and doing high stress aerobatics... you can cut that in half, or less.
Best advice is to do a voltage check at the end of each flight (before turning the RX off to prevent voltage rebound telling you there's more power left in the pack than what you really have...)
