Final answer:
To calculate the typing speed in words per minute, divide the total number of words typed, 900, by the total minutes spent typing, 15, to get a result of 60 words per minute.
Step-by-step explanation:
To solve how many words per minute a person can type when they type 900 words in 15 minutes, you would divide the total number of words typed by the number of minutes spent typing. Here is how you calculate it:
- Write down the total number of words typed, which is 900 words.
- Write down the total time spent typing, which is 15 minutes.
- Divide the number of words by the number of minutes to find the words per minute (WPM). So, you would calculate 900 words ÷ 15 minutes = 60 words per minute.
Therefore, if a person types 900 words in 15 minutes, they are typing at a speed of 60 words per minute.
