Which of the following is the most appropriate unit to describe the rate at which data is transferred using the internet?

A. Megabits per second, because the independent quantity is time in seconds and dependent quantity is amount of data in megabits
B. Seconds per megabit, because the independent quantity is time in seconds and dependent quantity is amount of data in megabits
C. Seconds per megabit, because the iIndependent quantity is amount of data in megabits and dependent quantity is time in seconds
D. Megabits per second, because the independent quantity is amount of data in megabits and dependent quantity is time in seconds ***

To find the most appropriate unit to describe the rate at which data is transferred using the internet, we need to consider the independent and dependent quantities involved. In this case, the independent quantity is time in seconds and the dependent quantity is the amount of data in megabits.

Option A. Megabits per second: This is the correct choice because it represents the rate of data transfer. The amount of data (dependent quantity) is divided by the time (independent quantity).

Option B. Seconds per megabit: This does not represent the rate of data transfer as the dependent quantity is divided by the independent quantity, which is not the correct arrangement for the rate.

Option C. Seconds per megabit: Again, this does not represent the rate of data transfer as the dependent quantity is divided by the independent quantity, which is not the correct arrangement for the rate.

Option D. Megabits per second: This is the correct choice because it represents the rate of data transfer. The amount of data (dependent quantity) is divided by the time (independent quantity).

Therefore, the correct answer is D. Megabits per second as it represents the rate at which data is transferred using the internet.

To get to this answer, you need to understand that the rate of data transfer is typically measured in megabits per second. The independent quantity is time in seconds, and the dependent quantity is the amount of data in megabits.
