Question 204823
A bird takes 30 minutes to make a 3 kilometer round trip between 2 trees. Flying 1/4 m against the wind on the first half of the trip takes the same time as flying 1/2 m with the wind on the return flight. Find the speed of the bird in still air and the speed of the wind.
----------
What does 1/4 m and 1/2 m mean?
