Final answer:
Sanna will take approximately 42.72 minutes to finish the rest of the assignment.
Step-by-step explanation:
To find out how long it will take Sanna to finish the rest of the assignment, we need to calculate the time taken to finish one problem. We can do this by dividing the total time taken to finish 14 problems by the number of problems.
Time taken to finish one problem = Total time taken / Number of problems = 25 minutes / 14 = 1.78 minutes per problem.
So it will take Sanna approximately 1.78 minutes to finish each problem. To find the time taken to finish the remaining 24 problems, we can multiply 1.78 minutes by 24, which gives us 42.72 minutes. Therefore, it will take Sanna approximately 42.72 minutes to finish the rest of the assignment.
