Question

Mark can type 45 words in 3 minutes. Which of the following is equivalent to that rate?

Answer 1

15 words per minute

Step-by-step explanation:

If Mark can type 45 words in 3 minutes.

The rate at which mark types is obtained below:

`\begin{gathered} \text{Rate}=\frac{Number\text{ of words}}{\text{Number of minutes}} \\ =\frac{45\text{ words}}{\text{3 minutes}} \\ =15\text{ words per minute.} \end{gathered}`

Therefore, Mark types at a rate of 15 words per minute.

Note: Since the options are not given here, any rate equivalent to 15wpm is the correct option.
