Find the length of a broken line AK, consisting of three links, if it is known that AB = 240 cm, the length of BC is 15 times less than AB, and the length of CK is 27 cm longer than BC.
Let us find the lengths of the links of the polyline:
AB = 240,
BC = 240: 15 = 16,
CK = 16 + 27 = 43.
The length of the entire polyline is equal to the sum of the lengths of the links:
AB + BC + CK = 240 + 16 + 43 = 299.
