$210$ words.

#### Explanation:

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

$\left(\text{120 words")/("60 seconds") = ("2 words")/("second}\right)$

$\text{1.75 minutes" xx "60 seconds" = "105 seconds}$

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

$\text{2 words"/"second" xx "105 seconds" = "210 words}$
