Final answer:
To determine how long it will take Sam to type 180 words at a rate of 16.25 words per minute, we divide the total words by the rate, which results in approximately 11.08 minutes.
Step-by-step explanation:
Sam can type 65 words in 4 minutes, so we need to find out how long it will take him to type 180 words. First, we calculate Sam's typing rate of words per minute by dividing the number of words by the number of minutes:
Rate = 65 words / 4 minutes = 16.25 words per minute.
Next, we use the calculated rate to determine the time it will take to type 180 words:
Time = Total Words / Rate = 180 words / 16.25 words per minute.
Now we perform the division:
Time = 180 / 16.25 ≈ 11.08 minutes.
Therefore, it will take Sam approximately 11.08 minutes to type 180 words.
