Final answer:
The velocity of the box is 20 meters per minute, as calculated by the distance divided by the time and then converted into meters per minute. . So the correct answer is D) 20 m/min.
Step-by-step explanation:
The student is asking about the velocity of a box that moved a certain distance on a factory conveyor belt. To find the velocity, we use the formula velocity = distance / time.
The box moved 4 meters in 0.2 minutes, which is equivalent to 4 meters / (0.2 minutes * 60 seconds/minute) = 4 meters / 12 seconds. To get the velocity in meters per minute, we multiply by 60 seconds/minute, which gives us 20 meters/minute. So the correct answer is D) 20 m/min.
