Question

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 1

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

Answer 2

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

Step-by-step explanation:

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

`v = (\Delta s)/(\Delta t)` (Eq. 1)

Where:

`\Delta s` - Travelled distance, measured in miles.

`\Delta t` - Time, measured in days.

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

`v = (11000\,mi)/(3\,mo* (30\,days)/(1\,mo) )`

`v = 122.222\,(mi)/(day)`

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