7500 words at 70 words per minute = 7500/70 = 107 minutes
3 hrs research......3 hrs = 180 minutes
180 + 107 = 287 minutes
at 2 hrs per day (thats 120 minutes per day)...
287/120 = 2.39 days.....hmmm..not sure if u should put 2 or 3....2 is actually the closest...but she cant finish in in 2 days...dont know if it is 2 or 3 because of the wording.
