Question

If you brush your teeth 10minutes a day, about how many hours do you brush in a year

Answer 1

152. 083hrs brushing your teeth a year if you brushed ten minutes per day.

Explanation:

There are 365 days in a year so you would multiply 10 times 365. That would result in 3,650 minutes per year. To convert that into hours you simply divide by 60 (3650/60). That gives you 152.083 hrs per year. Converting to hrs/mins/secs (if you wanted more accuracy), you would get approx 152 hrs 4 mins 58.8 seconds.

Answer 2

It would take you about 60 hours to brush your teeth in a year.

Steps:
Multiply 1 year by 10min: 365 x 10 = 3,650min
Divide that by 60(min) to get hours: 3,650/60 = 60.833
~ about 60 hours
