Jerry types 71 words per minute.
a. Write an equation to determine the amount of time it would take to type a given number of words. Define your variables.
b. How long would it take Jerry to type 2556 words?
c. If Jerry typed for 20 minutes, how many words did he type?
This is more clear
A) Think about what 71 words per minute means. It's a rate. For every minute, you will have typed 71 words. So to say how many minutes it will take you to type 71 words, you can say that the total number of words divided by the rate will give you the time. So you have T=W/71 where T is the total amount of time and W is a given total amount of words.
B) If we use our equation, we have T=2556/71=36, so it will take Jerry 36 minutes to type 2556 words at a rate of 71 WPM.
C) Again, using our equation, we have 20=W/71 which when we multiply by 71 on both sides, we'll get 1420=W, so Jerry would've typed 1420 words in 20 minutes if he typed at a rate of 71 WPM.
w = 71t
now you can answer the questions.
a. Let's define our variables:
- W: the number of words
- T: the amount of time it takes to type the words (in minutes)
- R: Jerry's typing rate (in words per minute)
So, the equation would be:
W = R * T
b. To determine how long it would take Jerry to type 2556 words, we can rearrange the equation:
T = W / R
Plugging in the given values:
T = 2556 / 71 ≈ 36.08 minutes
So, it would take Jerry approximately 36.08 minutes to type 2556 words.
c. If Jerry typed for 20 minutes, we can rearrange the equation again:
W = R * T
Plugging in the given values:
W = 71 * 20 = 1420 words
Therefore, Jerry would have typed 1420 words in 20 minutes.
a. To determine the amount of time it would take to type a given number of words, we can use the formula:
Time (in minutes) = Number of words / Words per minute
Let's define the variables:
- T: Time (in minutes)
- W: Number of words
The equation becomes:
T = W / 71
b. To find out how long it would take Jerry to type 2556 words, we can substitute the value of W into the equation:
T = 2556 / 71
Simplifying this equation will give us the answer in minutes.
c. If Jerry typed for 20 minutes, we can use the same formula to determine the number of words he typed:
W = T * 71
Substituting T = 20 into the equation, we can solve for W:
W = 20 * 71
