Answer 2

Answer:

A. 2

Step-by-step explanation:

The information tells us that in:

1.   1 hour we download 2 movies
2.  2 hours we download 4 movies
3.  2.5 hours we download 5 movies
4.  3.5 hours we download 7 movies

We want to know how many movies per hour we can download. We can express this as:

Movies/hour

So we have to divide the total movies downloaded by the hours it took to download:

1.  2(movies) / 1(hour) = 2 movies/hour
2.  4(movies) / 2 (hours) = 2 movies/hour
3.  5 movies / 2.5 hours = 2 movies/hour
4.  7 movies / 3.5 hours = 2 movies/hour

So the proportionality is 2 movies per hour
