Question

1. a. Derek reads at a rate of 25 words per minute. If he reads constantly until he is finished, how long would it take him to read a 225 word article?

Use the Slope-intercept form to solve. y=mx+b
y=total amt m=rate/slope x=minutes

Nine minuts.



b. If Derek’s friend Sarah reads the same 225 word article and it takes her 10 minutes to read it, who reads faster and how do you know?
PLS LIST HOW YOU GOT THE QUESTION...THANKS<3

Answer 1

The answer to part (a) is 9 minutes. The answer to part (b) is that Derek reads faster than Sarah.

Explanation:

a. To solve this problem, we can use the formula:

time = distance / rate

where "distance" is the number of words in the article and "rate" is the reading speed in words per minute. We want to find the time it takes Derek to read the article, so we can plug in the given values:

time = 225 / 25

time = 9

Therefore, it would take Derek 9 minutes to read the 225 word article if he reads constantly until he is finished.

b. To determine who reads faster, we can compare the reading rates of Derek and Sarah. Derek's reading rate is 25 words per minute, and Sarah's reading rate is:

225 words / 10 minutes = 22.5 words per minute

Since Derek's reading rate is higher than Sarah's reading rate, we can conclude that Derek reads faster than Sarah.

How I got the question:

Here are the steps I took to answer the question:

a. To solve for how long it would take Derek to read a 225 word article:

Step 1: Identify the given information

Derek's reading rate is 25 words per minute

The article has 225 words

Step 2: Identify the formula to use

We can use the formula: time = distance / rate, where "distance" is the number of words in the article and "rate" is the reading speed in words per minute.

Step 3: Plug in the values and solve

distance = 225 words

rate = 25 words per minute

time = distance / rate = 225 / 25 = 9 minutes

Therefore, it would take Derek 9 minutes to read the 225 word article if he reads constantly until he is finished.

b. To compare Derek's and Sarah's reading rates and determine who reads faster:

Step 1: Identify the given information

Derek's reading rate is 25 words per minute and it takes him 9 minutes to read the article.

Sarah took 10 minutes to read the same 225 word article.

Step 2: Calculate Sarah's reading rate

Sarah's reading rate = distance / time = 225 words / 10 minutes = 22.5 words per minute

Step 3: Compare the reading rates of Derek and Sarah

Derek's reading rate is 25 words per minute and Sarah's reading rate is 22.5 words per minute.

Step 4: Interpret the answer

Since Derek's reading rate is higher than Sarah's reading rate, we can conclude that Derek reads faster than Sarah.
