According to the meaning of the question, the total length of the route is 12km, and there is a stop every 1km.

It is set as the first stop at the beginning, that is, 0km, and then every 1 km.

Then divide by 12/ 1= 12, that is, set 12 stations from beginning to end.

Plus the first station, 1+ 12= 13,

Therefore, the total length of bus line 5 is 12km, and the distance between two adjacent stops is 1km. Then a * * * set up a 13 station.

Extended data:

This kind of problem belongs to the problem of planting trees in mathematics. The formula for planting trees is:

1, (planting at both ends): distance ÷ interval length+1= number of plants

2. (Only plant one end): distance ÷ interval length = number of plants.

3. (No planting at both ends): distance ÷ interval length-1 = number of plants.

Classification of tree planting problems in line segments;

1. If trees are planted at both ends of the tree planting line, the number of trees planted should be more than the number of segments to be divided 1, that is, the number of trees = the number of intervals+1.

2. If only one end of the tree planting line is planted with trees, then the number of trees is equal to the number of segments to be divided, that is, the number of trees = the number of intervals.

3. If no trees are planted at both ends of the tree planting line, the number of trees planted is less than the number of segments to be divided 1, that is, the number of trees = the number of intervals-1.

4. If trees are planted on both sides and ends of the tree planting route, the number of trees planted should be more than the number of segments to be divided 1, and then multiplied by 2, that is, trees = number of segments+1 and then multiplied by 2.
