Answer:
The journey would take 2 hours and 56 minutes for them to get from Paris to Marseille.
Explanation:
To find the answer you will first have to simplify it by making 10:56 into 10.56 and 13:12 into 13.12. Then you will subtract the biggest number into the lowest number which would be 2.56. Then after that you would make 2.56 into time basically I don't really know how I would explain that. I hope I answered your question!
