There are 180 minutes between 2 o'clock and 5 o'clock. This is calculated by finding the difference in hours (3 hours) and converting that to minutes (3 hours × 60 minutes/hour = 180 minutes).
To determine how many minutes until 4 o'clock, you need to know the current time. Subtract the current hour and minutes from 4:00. For example, if it's 3:30, there are 30 minutes until 4:00. If you provide the current time, I can give you the exact number of minutes.
