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!)

Answer:

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 ([tex]v[/tex]), measured in meters per second, is defined as:

[tex]v = \frac{\Delta s}{\Delta t}[/tex] (Eq. 1)

Where:

[tex]\Delta s[/tex] - Travelled distance, measured in miles.

[tex]\Delta t[/tex] - Time, measured in days.

If we know that [tex]\Delta s = 11000\,mi[/tex] and [tex]\Delta t = 3\,mo[/tex], then the average velocity is:

[tex]v = \frac{11000\,mi}{3\,mo\times \frac{30\,days}{1\,mo} }[/tex]

[tex]v = 122.222\,\frac{mi}{day}[/tex]

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