How many seconds are in 7.8 minutes?
I need to convert minutes to seconds, and I know that one minute has 60 seconds. So I can multiply the number of minutes by 60 to get the number of seconds. That means 7.8 minutes times 60 seconds per minute equals 468 seconds. I can check my answer by dividing 468 by 60 and seeing that I get 7.8, which is the original number of minutes.
