Carl and Lenny are trying to find Carl's keys that are beeping-he attached a device to beep when you whistle for this purpose. Carl is 4m away from the keys and they are at diffrent locations. The line connecting Carl and the keys is perpendicular to the line connecting Lenny and the keys. If the sound intensity at Lenny's location is two thirds as large as at Carl's,

A) how far is Lenny from the key's and...

B) how far is Lenny from Carl?
