A perpendicular bisector
this means the length IJ=JK and the angles IJB, BJK are 90° (and their congruent angles too)

but this does not mean AB=IK, because their lengths can be arbitrary
for a similar reason AJ=IJ is wrong, essentially the same statement but with half lengths
BI=BK is true, because it is a bisector of IK this means the sides IJ=JK and JB is a shared side, therefore also having the same length. We also know IJB and BJK are congruent angles, so all in all these are congruent triangle and therefore also share the side length
BI=AK is false, because we don't know where the intersection point j is on AB, it could split the length into any arbitrary ratio, in case these are two equal sides then it would be true, but it doesn't hold for all other possibilities

so BI=BK is the solution

Lin is reading a 47 page book . She read the first 20 pages in 35 minutes. If she keeps reading at the same pace, how long will
Damm [24]

Answer:

It will take her 1 hour, 22 minutes, and 15 seconds.

Step-by-step explanation:

We can find how long it takes her to read one page if we take 35 divided by 20.

35/20 equals 1.75, which means it takes Lin 1.75 minutes to read 1 page.

If we multiple 1.75 times the 47 pages of the book, we get 82.25.

But, this does not mean that it takes Lin 82 minutes and 25 seconds to read the book. Since there are only 60 seconds in one minute, we must convert the .25 to seconds.

.25 is equivalent to 1/4, and 1/4 of 60 seconds is 15 seconds.

It would also look like this  \frac{1}{4} *\frac{60}{1} = \frac{60}{4} = 15

So it took Lin 82 minutes and 15 seconds to read the book.

Or it took her 1 hour, 22 minutes, and 15 seconds to read the book.
