Alliyah and Abigail together can type 90 words per minute. How fast can Abigail type 700 words if Aliyah can type 300 words in 4 minutes?
~~~~~~~~~~~


Together they type 90 words per minute.


Individually, Aliyah can type 300 words in 4 minutes, or  300/4 = 75 words per minute.


Hence, Abigail types 90-75 = 15 words per minute.


To type 700 words, Abigail needs 700%2F15 = 46 2%2F3 minutes, or 46 minutes and 40 seconds.     ANSWER

Solved.
