Question

She needs to unpack 38 boxes. if each box takes the same amount of time. and she can unpack 4 boxes in 3 hours, how long will it take to unpack 38 boxes

Answer 1

It will take 28.5 hours

Explanation:

Make the boxes amount compatible to divide with 38

4/2=2

3/2=1.5

When you divide one part of the boxes and hours, you divide the other half too. So you divide 3 by 2, which is 1.5

Then you divide 38 by 2 which is 19

Then 19 times 1.5 to find out how many hours, which gives you 28.5
