20 birds migrate on a seasonal basis from one lake to another, searching for food. If they fly from lake Jim to lake Disney in one season, which is 50 miles apart, then the next season they fly from lake Disney to lake London, 60 miles apart, calculate the combined distance all of the birds have traveled in the two seasons.
The birds' flying distance between Lake Jim through lake Disney to lake London is 50+60 = <<50+60=110>>110 miles.
Since each bird flies the 110 miles distance while migrating, the combined distance they fly together is 110*20 = <<110*20=2200>>2200 miles.
