Answer 2

Understanding the Question

The question states that Sasha wants to watch a movie about school, while Pasha wants to watch a movie about heroes. If they both watch the movies together, it will take them 2 hours and 53 minutes. However, if they each watch their own movie, Sasha will spend 17 minutes more than Pasha. We need to determine the duration of each movie and find the individual times for Sasha and Pasha.

Finding the Duration of Each Movie

To find the duration of each movie, we need to solve a system of equations based on the given information. Let's assume the duration of the movie about school is x minutes and the duration of the movie about heroes is y minutes.

1. If they both watch the movies together, it will take them 2 hours and 53 minutes, which is equivalent to 173 minutes. - Equation 1: x + y = 173

2. If they each watch their own movie, Sasha will spend 17 minutes more than Pasha. - Equation 2: x = y + 17

Now, we can solve this system of equations to find the values of x and y.

Solving the System of Equations

To solve the system of equations, we can use substitution or elimination. Let's use substitution.

From Equation 2, we can substitute the value of x in Equation 1:

(y + 17) + y = 173 2y + 17 = 173 2y = 173 - 17 2y = 156 y = 156 / 2 y = 78

Now, we can substitute the value of y in Equation 2 to find the value of x:

x = 78 + 17 x = 95

Therefore, the duration of the movie about school (Sasha's movie) is 95 minutes, and the duration of the movie about heroes (Pasha's movie) is 78 minutes.

Answer

Based on the given information, the movie about school (Sasha's movie) has a duration of 95 minutes, and the movie about heroes (Pasha's movie) has a duration of 78 minutes.
