6. (a)
But, given that A takes $20 \mathrm{~min}$ utes more
i.e.
$$
\text { 1unit } \longrightarrow 20
$$
$\therefore 4$ units $\longrightarrow 20 \times 4=80 \mathrm{~min}=\frac{80}{60} \mathrm{hrs}=1 \frac{1}{3} \mathrm{hrs}$ i.e. time taken by A to reach destination $=1 \frac{1}{3} \mathrm{hrs}$
