I'm going to start by making some basic assumptions:
Horizontal strip length | Horizontal length (cm) | Vertical strip length (squares) | Vertical length (cm) | Total length of rope so far (cm) |
---|---|---|---|---|
2 | 1 | 1 | 0.5 | 1.5 |
3 | 1.5 | 2 | 1 | 4 |
4 | 2 | 3 | 1.5 | 7.5 |
5 | 2.5 | 4 | 2 | 12 |
6 | 3 | 5 | 2.5 | 17.5 |
7 | 3.5 | 6 | 3 | 24 |
8 | 4 | 7 | 3.5 | 31.5 |
9 | 4.5 | 8 | 4 | 40 |
10 | 5 | 9 | 4.5 | 49.5 |
11 | 5.5 | 10 | 5 | 60 |
12 | 6 | 11 | 5.5 | 71.5 |
Two trains set off at the same time from each end of a single straight railway line. A very fast bee starts off in front of the first train and flies continuously back and forth between the two trains. How far does Sidney fly before he is squashed between the two trains?
An observer is on top of a lighthouse. How far from the foot of the lighthouse is the horizon that the observer can see?
