Final answer:
The ft rate of change described in the question is constant at 3060 ft/min for all given scenarios, indicating there is no acceleration, as the movement rate does not change over time.
Step-by-step explanation:
The rate of change in feet per minute can be determined by calculating the change in distance traveled over the change in time.
Starting with the provided rates, 255 ft in 1/12 minute, 510 ft in 1/6 minute, and 3060 ft in 1 minute, we need to convert these to a common time unit to compare them.
To find the rate of change in ft/min for each case, we multiply 255 ft by 12 to get 3060 ft/min, 510 ft by 6 to get 3060 ft/min, and the given 3060 ft/min remains unchanged.
Each scenario yields a rate of 3060 ft/min, indicating that the student's ft rate of change is constant at 3060 ft/min. This scenario does not involve acceleration, as the rates of change are consistent.
