Physics HELP!!

A loudspeaker is placed between two observers who are 113m apart, along the line connecting them. If one observer records a sound level of 51.8dB and the other records a sound level of 75.8dB, how far is the speaker from each observer?
Enter the longest distance first.

    I2/I1 = (r2)^2/(r1)^2
    square root of (I2/I1) = r2/r1
    This will be the difference between the two.
    Therefore (distance between the two people/ square root of (I2/I1)) = smallest distance from loud speaker.
    And distance between the two people minus the smallest distance is the largest distance.

    Log10(I2/I1) = 1/10 (dB2 - dB1)

    10^[0.1(dB2-dB1)] = I2/I1
