Total: 276 km
Explicación paso a paso:
[tex]\frac{1}{4}[/tex] x + [tex]\frac{1}{3}[/tex] x + 115 = x
115 = 1x [tex]-\frac{1}{4}[/tex] x [tex]-\frac{1}{3}[/tex] x
115 = [tex]\frac{12}{12}[/tex] x [tex]-\frac{3}{12}[/tex] x [tex]-\frac{4}{12}[/tex] x
115 = [tex]\frac{5}{12}[/tex] x
115 ÷ [tex]\frac{5}{12}[/tex] = x
[tex]\frac{1.380}{12}[/tex] ÷ [tex]\frac{5}{12}[/tex] = x
276 = x
