The first volume of mathematics in the second grade of primary school exercises: every two trees are 8 meters apart. How many meters is it from the first tree to the seventh tree?
There are two answers.
1, on the straight road ... one more tree.
7- 1=6 (segment)
8× 6 = 48m
2. On a closed road, such as a circular road ... there are as many trees as parts.
7×8=56 meters
