Increasing range with combining units in cities

Can anyone explain how you can get more range out of units when moving them into other cities? I've found that if I make some bombers in city A, move them to city B, create additional bombers in city B I can move ALL the bombers further than I would have been able to move the original bombers from city A. It seems the act of adding to the units enables them to move further. I'm not sure how this works and I'd love to know how far back I can get so that I can still reach my goal...sometimes I start too far back and then I run out of range before the intended target and other times I start too close and don't have enough to complete the goal. Does this make sense?

It's as simple as that units' range is added up just like if you did some sort of mathematical average between all the ranges that your units have. You should already know that this happens wherever you stack your units, not just cities.

In the case you are merging units of the same type it's a kind of average... in other cases (mixed unit pool), it is the unit with less range that defines how far the puck can move. Somehow obviously.
