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?

Answer 1

105 min

Answer 2

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

Answer 3

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..

Answer 4

Ok. My answer was 105mins But converted to 1hr & 45 mins.

Thanks!

Answer 5

I disagree with Kazz.

1 hour = 60 minutes

105 - 60 = 45 minutes

105 minutes = 1 hour and 45 minutes

Answer 6

oh yes.. sorry:)

Answer 7

Thank you both

Answer 8
