Answer:

Option (D)

Explanation:

Velocity of jet with respect to air = velocity of jet with respect to ground - velocity of air with respect to ground

Vj,a = Vj,g - Va,g

600 mph east = Vj,g - 0

Beacause air is not moving

Vj,g = 600 mph east

Thus, the velocity of jet with respect to ground is 600 mph towards east.
