Answer: 59.5 minutes.
Step-by-step explanation:
1. You have the following information given in the problem above:
- 8 songs are 4.25 minutes long.
- 3 songs are twice as long as each of the others.
2. Therefore, the total time of 8 songs is:

3. And the total time of the 3 songs is:

4. Therefore, you have that the result is:

A(-2, 2), B(4, 2), C(-6, -1), D(0, -1)
AB = CD = 4 - (-2) = 4 + 2 = 6
BD = AC. Use the formula of a distance between two points:

Substitute the coordinates of the points B and D:

BD = AC = 5
