PHYSICS HELP! Relative velocity?

Posted on 2015-10-14 07:36:00 in Physics by RICHIE

When a bird flies due south with respect to the air, it can maintain sustained flight speeds of 35 m/s. This bird was flying with the wind, which was moving at 23 m/s.

A. What was the bird's airspeed - its speed relative to the air?

B. What would the bird's flight speed be if the wind blew 23 m/s due west?

C. What would the bird's flight speed be if the wind blew 23 m/s due north? What would be the bird's flight direction with respect to the ground?

Please help, please show me how to do this? Very confused.
