Answer:
It will take 28.5 hours
Step-by-step 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
