Which roads do you think short?

Method. 1 Made a miniature copy as a model of orthogonal road city or radially circle road city like this photograph. Orthogonal road city Radially circle road city

Method 2. Throw two coins. Then, measure the distance and distance along road between the points which two coins fell.

Measure the distance with a ruler.

Measure the distance along road with string.

Method. 3 Process the collected date using EXCEL. What’s the ratio?

Result Distance along road 1 44. 45 63. 14 1. 42 1 44. 25 51. 43 1. 162 2 49. 89 70. 84 1. 42 2 22. 40 28. 81 1. 286 3 52. 4 73. 1 1. 395 3 23. 94 27. 25 1. 138 4 12. 59 1. 41 4 42. 30 44. 68 1. 056 5 36. 2 49. 57 1. 369 5 33. 75 35. 59 1. 055 17. 75 Ratio Orthogonal road city Distance along road Ratio Radially circle road city
