A migrating bird flew across a lake at an average speed of 18 meters per second. Was the distance that the bird flew across the lake less than 21 kilometers? (1 kilometer = 1000 meters)
(1) It took the bird less than 20 minutes to fly across the lake.
(2) It took the bird less than 0.4 hour to fly across the lake.
