Problem Analysis

To solve this problem, we need to find the total distance from St. Petersburg to Murmansk through Petrozavodsk. We are given that the distance from St. Petersburg to Petrozavodsk is 401 km, and the distance from Petrozavodsk to Murmansk is 643 km more than the distance from St. Petersburg to Petrozavodsk.

Solution

Let's break down the problem step by step:

1. The distance from St. Petersburg to Petrozavodsk is 401 km. 2. The distance from Petrozavodsk to Murmansk is 643 km more than the distance from St. Petersburg to Petrozavodsk. 3. To find the total distance from St. Petersburg to Murmansk through Petrozavodsk, we need to add the distances from St. Petersburg to Petrozavodsk and from Petrozavodsk to Murmansk. 4. Adding the distances, we get: - Distance from St. Petersburg to Petrozavodsk: 401 km. - Distance from Petrozavodsk to Murmansk: 401 km + 643 km = 1044 km. - Total distance from St. Petersburg to Murmansk through Petrozavodsk: 401 km + 1044 km = 1445 km.

Answer

The total distance from St. Petersburg to Murmansk through Petrozavodsk is 1445 km.
