Use the information to answer the question. Liz types at a rate of 25 words per minute. The graph shows the number of words typed over time by 4 other students.
Which student types at the same unit rate of words per minute as Liz?
please help!

Britt:

This is because if she types 25 words in one minute then that means she can type 50 words in 2 minutes (just multiply by 2). The only person on the graph who can type 50 words in 2 minutes is Britt.

Hope this helps! Any questions let me know :)
