The arctic tern flies from the Arctic to the Antarctic and back every year, a total distance of 22,000 miles! In late summer, the terns start their migration south, and it takes about 3 months to go the 11,000 miles. What is the average velocity, in miles per day, that these birds travel? (Remember, velocity also includes direction!)

The artic tern flies 11000 miles about 3 months at an average velocity of 122.222 miles per day.

Explanation:

Let suppose that each month is equivalent to 30 days, from Mechanical Physics we understand that average velocity (), measured in meters per second, is defined as:

(Eq. 1)

Where:

- Travelled distance, measured in miles.

- Time, measured in days.

If we know that and , then the average velocity is:

The artic tern flies 11000 miles about 3 months at an average velocity of 122.222 miles per day.
