Megabits per second; because the independent quantity is time in seconds and dependent quantity is amount of data in megabits.

Seconds per megabit, because the independent quantity is time in seconds and dependent quantity is amount of data in megabits

Seconds per megabit, because the independent quantity is amount of data in megabits and dependent quantity is time in seconds


Megabits per second, because the independent quantity is amount of data in megabits and dependent quantity is time in seconds

Answer 2

any ideas on this one ?

Answer 3

I'm guessing A

Answer 4

first clue is rate is sometimes used for speed and speed is miles per hour
in other words, the "time" is after the "per"

so megabits per second is a good guess.
the "dependent" vs "independent" stuff is just a complicated way to say
how much the first variable changes (i.e. megabits) depends on the second variable (i.e. the seconds)
in other words, if you want more megabits of stuff, then you need more seconds

megabits is the dependent variable
seconds is the independent variable.
