You can do the rule of three,
You first have to convert one minute to seconds, which is 60 sec then you have to convert 1.75 minutes to seconds, which is 105 sec.
if in 60 seconds Dorothy types 120 words, then in 105 seconds Dorothy types x words
105*120 = 12600/60, in 1.75 minutes Dorothy types 120 words.
