The problem you must solve is:

How many times louder is a 60 dB sound than a 20 dB sound?
How many times more energy is released by a magnitude 6 earthquake than by a magnitude 2 earthquake?
When you are 2 meters away from the speakers at a concert, the sound level is 130 db. How far away should you sit to reduce the level to 110 dB?

To get full credit for this write-up, you should:

Answer all parts of the problem.
Show your justification for every step in your solution. Use clear, mathematically accurate language.
Label all numbers with the units they represent (e.g., 0.3048 ft/meter).
Clearly state your conclusions using complete English sentences (for example, "Jill needs to add 43 gallons of water to her pool")
