#210# words.

Explanation:

#120# words per minute can be expressed as #2# words per second because there are #60# seconds in a minute, and

#("120 words")/("60 seconds") = ("2 words")/("second")#

#"1.75 minutes" xx "60 seconds" = "105 seconds"#

If Dorothy types #2# words per second, then in #105# seconds, she will type #210# words.

#"2 words"/"second" xx "105 seconds" = "210 words"#
