Final answer:
The velocity of a rocket ship that travels 32,000 km North in 2.5 hours is 12,800 km/h, which is option A.
Step-by-step explanation:
The velocity of a rocket ship that travels 32,000 km North in 2.5 hours can be calculated using the formula for velocity, which is the displacement divided by the time taken. To find the velocity (v):
v = displacement / time = 32,000 km / 2.5 h = 12,800 km/h.
Therefore, the correct answer is A) 12,800 km/h.
