.

u + v = 3 miles per hour u - v = 1.5 miles per hour. -------------------------------------Add the two equations. Answer. The bird's air speed u = 2.25 miles per hour. The wind speed v = 0.75 mph.

Solved.

-------------------

It is a typical "tailwind and headwind" word problem.

I don't think any birds fly at such a low air speed.
