Solution

The correct option is A $$154$$ words.
In $$1$$ minute, Veronica can type $$28$$ words.

In $$5\dfrac{1}{2}$$ minutes, Veronica can type $$=5\dfrac{1}{2}\times 28$$ words

                                                          $$=\dfrac{11}{2}\times 28$$ words
                                                          $$=154$$ words

Hence, Veronica can type $$154$$ words in $$5\dfrac{1}{2}$$ minutes.
