Answer 2

Task Solution

The student spent 25 minutes solving a problem and 10 minutes solving the equations. Each equation took 5 minutes to solve. We can use this information to calculate the number of equations the student solved.

To find the number of equations the student solved, we can use the following equation: Total time spent = Time spent on problem + Time spent on equations 25 minutes = 10 minutes + 5 minutes * Number of equations

Let's solve for the number of equations: 25 minutes = 10 minutes + 5 minutes * Number of equations 25 minutes - 10 minutes = 5 minutes * Number of equations 15 minutes = 5 minutes * Number of equations Number of equations = 15 minutes / 5 minutes Number of equations = 3

So, the student solved 3 equations.

Conclusion

The student solved 3 equations after spending 25 minutes on a problem, with 10 minutes dedicated to solving the problem and 5 minutes for each equation.
