Problem Analysis

Sergey left his house and was heading towards his friend's place. After walking 120 meters away from his house, he realized that he had lost his keys. Sergey then turned back and walked 70 meters, where he found his keys. He continued his journey and walked another 50 meters before meeting his friend. We need to determine the distance from Sergey's house where he met his friend.

Solution

To find the distance from Sergey's house where he met his friend, we need to calculate the total distance Sergey walked from his house.

1. Sergey walked 120 meters away from his house and then turned back, so he walked an additional 120 meters to return to his house. 2. After finding his keys, Sergey walked 50 meters before meeting his friend.

To calculate the total distance, we add the distances Sergey walked: 120 meters (away from the house) + 120 meters (returning to the house) + 50 meters (to meet his friend) = 290 meters.

Therefore, Sergey met his friend at a distance of 290 meters from his house.

Answer

Sergey met his friend at a distance of 290 meters from his house.
