during a reading test, mike reads a passage with 640 words, it takes him 4 minutes to read the passage. How many would it take mike to read a passage that has 800 words.
To find out how long it would take Mike to read a passage with 800 words, we can set up a proportion:
640 words / 4 minutes = 800 words / x minutes
Cross multiplying:
640 * x = 800 * 4
Dividing both sides by 640:
x = (800 * 4) / 640
x = 5 minutes
So it would take Mike 5 minutes to read a passage with 800 words.
