Hi there! To find the unit rate for the number of books Jenny reads, we can divide the number of books read by the amount of hours. 3/7.5 is 0.4 or 4/10 in fraction form. Jenny can read 4/10 of a book in one hour.

We are given that Jenny can read 3 books in 7.5 hours. To find the number of books Jenny can read in one hour, all we need to do is divide 3 by 7.5, which gives us 0.4 books. Therefore, Jenny can ready 0.4, or 2/5 of a book in one hour. Hope this helped!

Answer:

Therefore the required value of $\overline{BD}$ is 20 units.

Step-by-step explanation:

Line Segment: Line segment is a portion of a line whose has two end points.

Given that point C is on the line segment $\overline{BD}$ .

$\overline{BD}$ = 5x , $\overline{BC}$ = 4x and $\overline{CD}$ = 4

C is the point of the line segment of $\overline{BD}$ .

So we can write

$\overline {BD}= \overline{BC}+\overline{CD}$

Putting the values of $\overline{BD}$ , $\overline{BC}$ and $\overline{CD}$

5x=4x+ 4

⇒5x-4x= 4

⇒x=4

So we get the value of x.

To get the value of $\overline{BD}$ , we need to put the value of x in the value of $\overline{BD}$ .

Therefore,

$\overline{BD}$ = 5×4

=20

Therefore the required value of $\overline{BD}$ is 20 units.
