In the schoolyard there is a swing that hangs from the tree branch. The swing is 50cm from the ground and the tree grows at a rate of 5cm per year.

**How high will the swing be in 10 years?**

#### Solution

The trees increase in height as the canopy grows. A branch that leaves the trunk at a certain height of the base will always remain at the same height. Thus **the swing will continue 50cm from the ground** In 10 years.
