Question

A student can type 252 words in 4.5 minutes. What is the unit rate in words per minute

Answer 1

Number of words: 252

Time: 4.5 minutes

To find the unit rate r in words per minute, we use the formula:

`r=(W)/(t)`

Where W is the number of words, and t is the time elapsed. Using the information of the problem:

`r=(252)/(4.5)=56\text{ words per minute}`
