Final answer:
Jennifer reads 4/7 of a chapter in 1/6 of an hour. By setting up a proportion and solving, we find she can read about 3.43 chapters in one hour, but since she cannot read a fraction of a chapter, we round down to 3 full chapters.
Step-by-step explanation:
To determine how many chapters Jennifer can read in one hour, we need to find the rate at which she reads. Since Jennifer read 4/7 of a chapter in 1/6 of an hour, we can set up a proportion to find the number of chapters she can read in a full hour.
Let's call the number of chapters she can read in one hour c. The proportion will be:
(4/7) chapters / (1/6) hour = c chapters / 1 hour
We solve for c by cross-multiplying:
(4/7) * 1 = (1/6) * c
This simplifies to:
4/7 = c/6
To solve for c, we multiply both sides by 6:
c = (4/7) * 6
This results in:
c = 24/7
Therefore, Jennifer can read 24/7, or approximately 3.43 chapters in one hour. We need to round down to the nearest whole chapter since she can't read a fraction of a chapter. So, the answer is 3 chapters, which corresponds to option C.
