Noting that the fly is stationary (on your head), the speed of the fly is ZERO with respect to your nose, i.e. there is no motion. Remember that the speed (or velocity) is the derivative of the distance over time: v = dx/dt. If the change in x is ZERO (dx=0), hence dx/dt = 0. v=0.

The fly's speed relative to you is 0. The fly's speed relative to the ground is same as the car.
