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?

105 min

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

Math  kazz, Thursday, December 13, 2012 at 9:46pm
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..

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

I disagree with Kazz.
1 hour = 60 minutes
105  60 = 45 minutes
105 minutes = 1 hour and 45 minutes

oh yes.. sorry:)
