You can put this solution on YOUR website! with a tailwind, a bird flew at a ground speed of 3 miles per hour. flying the same path against the same wind, the bird travels at a ground speed of 1.5 miles per hour. what is the bird's air speed? what is the wind speed?
------
Equations:
b + w = 3 mph
b - w = 1.5 mph
----
Add and solve for "b":
2b = 4.5
b = 2.25 mph (bird's speed in still air)
-----
Solve for "w":
b + w = 3 mph
2.25 + w = 3 mph
w = 0.75 mph
