Solution Steps

Step 1: Determine the number of hours an on-site training course takes

Given that each on-site training course takes 10 hours, the number of hours an on-site training course takes is \( x = 10 \).

Step 2: Determine the number of hours an online training course takes

Given that each online training course takes 15 hours, the number of hours an online training course takes is \( y = 15 \).

Step 3: Calculate how many more hours each online training course takes than each on-site training course

To find how many more hours each online training course takes than each on-site training course, subtract the number of hours of an on-site course from the number of hours of an online course: \( y - x = 15 - 10 = 5 \).

Final Answer

\(\boxed{5}\)
