Final answer:
The cloud's velocity is calculated by dividing the displacement (3,150 meters) by the time (12.5 minutes), resulting in a velocity of 252 meters per minute to the east.
Step-by-step explanation:
To calculate the cloud's velocity, we need to use the formula for velocity, which is the displacement divided by the time taken. In this case, the cloud drifted 3,150 meters to the east in 12.5 minutes, so the velocity can be found as follows:
Velocity = Displacement / Time = 3,150 meters / 12.5 minutes = 252 meters per minute.
Since the cloud moved to the east, the correct answer is:
A) 252 meters per minute to the east
