Meredith took 15 minutes to unpack 4 boxes of books. If she unpacked a total of 28 boxes, how long did it take her to unpack all the boxes?

That's what I got & my teacher marked it wrong. Is that 1hr & 45 mins

if we convert it into hours:

in 1 hour there are 60 min

so, 105 min ( 1hr/ 60 min)

it's 1 hr. and 75 min.

maybe you can ask your teacher about that..

I disagree with Kazz.

1 hour = 60 minutes

105 - 60 = 45 minutes

105 minutes = 1 hour and 45 minutes
