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?

Answer 1

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

Explanation:

Answer 2

The birds travel at an average velocity of 122.2 miles per day

Explanation:

The arctic terns fly a total distance of 22,000 miles in their yearly migration from the Arctic to the Antarctic and back again.

The average speed is the ratio between the total distance traveled by the time they took to travel.

Assume we take an average month of 30 days, then the time the arctic terns take to travel the 11,000 miles back is 30*3= 90 days.

The average velocity is

`\displaystyle v=(11,000)/(90)=122.2`

v=122.2 miles/day

The birds travel at an average velocity of 122.2 miles per day
