Which statement correctly identifies a common mistake when calculating elapsed time?

Counting the minutes to the next hour is an unreliable method.

Subtracting times like decimal numbers (e.g., $5.15 - 3.45$) gives the correct answer.

Forgetting that time is based on 60 minutes per hour can lead to errors.

Adding the hours before the minutes always results in a mistake.
