It took Melanie 161 minutes to do her homework last night. About how many hours did she spend on her homework?

Well there 60 minutes to one hour so you would take 161/60

2 hours

take 161/60 =

161-60-60=41min left so i would say
2hours and 41 minutes

To find out how many hours Melanie spent on her homework, you need to convert the minutes to hours. Since there are 60 minutes in one hour, divide the number of minutes by 60.

161 minutes ÷ 60 = 2.68 hours

So, Melanie spent about 2.68 hours on her homework last night.
