Question 1
There are three islands in the sea (the dark grey regions).
Two birds are on island C and want to reach island A. We know that:
- The birds can move through cells only up, down, left or right, and always take the fastest route.
- The black bird can fly over 2 sea cells per hour and must rest on land for 1 hour after flying over 4 cells.
- The white bird can fly over 4 sea cells per hour and must rest on land for 2 hours after flying over 4 cells.
- On land, both birds walk at 1 cell per hour.
If they set out at the same time, which bird reaches island A sooner?
