Solve Time Conversion: Convert 3hr to Minutes (hr to min)

Q: Why do I multiply by 60 instead of dividing?

When converting from a larger unit to a smaller unit, you always multiply! Think about it: 3 hours contains many more minutes, so the number gets bigger. Hours → Minutes = Multiply by 60

Q: How can I remember the conversion factor?

Remember that there are 60 seconds in a minute and 60 minutes in an hour. You can also think: 'In one hour, the minute hand goes around the clock face 60 times!'

Q: What if I need to convert minutes back to hours?

To go from minutes to hours, you do the opposite operation: divide by 60. For example: $ 180 \text{ minutes} \div 60 = 3 \text{ hours} $

Q: Are there any shortcuts for common time conversions?

Yes! Memorize these: 30 minutes = 0.5 hours, 90 minutes = 1.5 hours, 120 minutes = 2 hours. But when in doubt, always use multiply by 60 for hours to minutes.

Q: What if the problem involves mixed units like 2 hours 30 minutes?

Convert each part separately, then add: $ 2 \times 60 + 30 = 120 + 30 = 150 \text{ minutes} $. Always convert the hours first!
