A. 93.75 words per minute

Step-by-step explanation:

Ingrid typed a total of 2500 + 5000 + 3750 = 11,250 words in 300 minutes, for an average speed of 11250/300 = 37.5 words per minute.

Bobby typed a total of 1500 + 12000 = 13,500 words in 240 minutes, for an average speed of 13500/240 = 56.25 words per minute.

Their total output was ...

37.5 wpm + 56.25 wpm = 93.75 words per minute
