Answer 1

Problem Analysis

We are given that Kolya completed his math homework in 15 minutes, his Russian language homework in 10 minutes, and his reading homework took 15 minutes longer than his Russian homework. We need to determine the time it took Kolya to complete his reading homework.

Problem Solution

Let's assume the time it took Kolya to complete his reading homework is x minutes. We can set up the following equation based on the given information:

Time for reading homework = Time for Russian homework + 15 minutes

x = 10 + 15

Simplifying the equation, we find:

x = 25

Therefore, it took Kolya 25 minutes to complete his reading homework.

Answer

Kolya took 25 minutes to complete his reading homework.
