Answer:
<h2>2.6</h2>
Step-by-step explanation:
To solve this, we need to use the Pythagorean theorem to solve this.
The way to solve is by solving for AD by using triangle CAD and then using that result to solve for BD.
3.4² + b² = 6.5²
11.56 + b² = 42.25
42.25 - 11.56 = b²
b = √30.69
b = 5.53985559 or about 5.5
4.9² + b² = 5.5²
24.01 + b² = 30.69
30.69 - 24.01 = 6.68
b = √6.68
b = 2.58456959666 or about 2.6
<h2>EDIT: the other user is incorrect, here's why</h2>
3.4 + 4.5 = 7.9
6.5² + 4.9² = 7.9²
66.26 doesn't equal 62.41

<em>What does 6 1/2 mean in this situation</em>
<em>
a. Zhen spends 6 1/2 hours working for every hour of the completed audiobook.
</em>
<em>b. Zhen completes 6 1/2 audiobooks in an hour.
</em>
<em>c. Zhen spends 6 1/2 hours working per audiobook.</em>
It means that Zhen needs 6 1/2 working hours to record 1 hour of the audiobook. Zhen needs to work more than one hour to record one hour of the audiobook, because besides recording, he also needs to research and edit.
