## Task 2 - 030612

A pioneer group set off from the city to a holiday camp by bus at 16:00.

When they had covered nine-tenths of the distance, the pioneers had to get off the bus 2 km before the camp because the bus could no longer travel on the forest road leading to the camp. They needed half an hour for the rest of the journey and arrived at the camp at 17:00.

At what speed did the bus travel? (How many kilometers did it cover in one hour?)
Given that $\frac{1}{10}$ of the distance is $2 \mathrm{~km}$, if the bus covers $\frac{9}{10}$ of the route in 30 minutes, a distance of $18 \mathrm{~km}$ has been traveled. This amounts to $36 \mathrm{~km}$ in one hour.
