## Task 1 - 330521

On a street in a small town, there are a total of 47 street lamps on the left and right side of the road. On each side of the street, the distance between any two adjacent lamps is $35 \mathrm{~m}$. On the left side of the road, there is a lamp exactly at the beginning and at the end of the street. How long is this street?
There must be exactly one more lamp on the left side of the road than on the right side. If the lamp at the end of the street on the left side is not counted, then there are the same number of lamps on both sides of the street, which is $46: 2=23$ pieces.

Therefore, the length of the street is $23 \cdot 35 \mathrm{~m}=805 \mathrm{~m}$.
