Let the distance be x km
therefore by bus = $\frac{4}{5}x$ km
By matatus = $\frac{2}{3}$ x $\frac{1}{5}x$ = $\frac{2}{15}x$
Walked = x - ($\frac{4}{5}x$ + $\frac{2}{15}x$)
= x - $\frac{14}{15}x$ = $\frac{1}{15}x$
$\frac{4}{5}x$ - $\frac{1}{15}x$ = 55
$\frac{12x - x}{15}$ = 55; $\frac{11}{15}x$ = 55
therefore x = $\frac{55\times 15}{11}$ = 75 km
