Harry and Sally are sitting on opposite sides of a circus tent when and elephant trumpets a loud blast. If Harry experiences a sound intensity level of 65dB and Sally only 55dB, what is the ratio of the distance between Sally and the elephant to the distance between the elephant and Harry?

2. Relevant equations

I=P/(4piR^2)

B=10log(I/10^-12)

3. The attempt at a solution

65=10log(I/10^-12)

so I(harry)=10^-5.5

55=10log(I/10^-12)

so I(sally)=10^-6.5

*I have no idea where to go from here or if that was even the correct first step to take.

If I knew the Power(P), I would be able to find the radius and get distance from that, but I don't have a way to calculate that.
