anonymous · Answer

$$\frac{ 1 }{ 3x } + \frac{ 1 }{ x } = \frac{ 1 }{ 2 }$$

anonymous · Answer

So by finding the LCD it will turn to $$\frac{ 3 }{ 3x } + \frac{ 3 }{ 3x } = \frac{ 1 }{ 2 }$$

anonymous · Answer

long story short the answer is 4 but im trying to work it out on here

anonymous · Answer

$$\frac{ 3 }{ 3x }+\frac{ 3 }{ 3x } = \frac{ 2 }{ x}$$

anonymous · Answer

I have a question - wouldn't it be (x - 3) for Carl, not 3x? Because he doesn't take 3 times as long, he goes three times FASTER. I could be wrong, though.

anonymous · Answer

$$\frac{ 2 }{ x } =\frac{ 1 }{ 2 } = 4$$
