## Task 3 - 020513

Two pioneer groups want to go on a hike to Neuendorf, which is 12 kilometers away, on a Sunday. The first group plans to set off at 8:00 AM. They cover 4 km per hour.

The other group will go on a bike ride and can travel 12 km per hour.

When should they set off if both groups want to arrive in Neuendorf at the same time?
The first group hikes $4 \mathrm{~km}$ per hour and reaches the destination, which is $12 \mathrm{~km}$ away, in 3 hours, meaning they arrive in Neuendorf at 11:00 AM.

The second group covers 12 km per hour and only needs 1 hour to reach the destination. Therefore, they must start in Neuendorf at 10:00 AM.
