## Task 3 - 150513

A group of pioneers went on a bicycle tour. They started within a town and reached the town's exit after $800 \mathrm{~m}$ of cycling. After that, they covered five times this distance and then took a break.

After another $14 \mathrm{~km}$, they had lunch. The remaining distance to their destination was $2.5 \mathrm{~km}$ less than the distance they had already covered.

Determine the total length of the route from the start to the destination!
Addition of the partial distances yields

$$
s=(800 m+5 \cdot 800 m+14000 m)+(800 m+5 \cdot 800 m+14000 m)-2500 m=35100 m
$$

The cycling tour was $35 \mathrm{~km}$ and $100 \mathrm{~m}$ long.
