Total hours is 3.35 hours
Explanation:
Given:
convert 3 hours 21 minutes to decimal hours
We know:
1 hour = 60 minutes
and
1 minute = 60 seconds
1 minute = 1 / 60 hours
So,
21 minutes = [tex]\frac{21}{60} hours[/tex]
= 0.35 hours
Total hours would be = 3 hours + 0.35 hours
= 3.35 hours
Therefore, total hours is 3.35 hours
