Explanation:

Step1: Find the average study - time per student for the group of 13 students.

The total time for 13 students is 637 minutes. So the average time per student is $\frac{637}{13}=49$ minutes.

Step2: Predict the time for 125 students.

Multiply the average time per student by 125. So the predicted time is $49\times125 = 6125$ minutes.

Answer:

It will take them 6,125 minutes.
