Speedo · Answer 1

The distance the bird flies is (17,000 + 600 + 14,400) = 32,000 km.

His average speed is (32,000 km) / (122 days) = 262.3 km/day.

The bird ends up (17,000 - 600 + 14,400) = 30,800 km north

from where he started.

His average velocity is (30,800 km) / (122 days) = 252.5 km/day north.
