My expected outcome with the below code should be:

The route with the biggest time differential is 10013 EB 97 WB 106 with a time difference of 9 minutes.

However, I am getting something completely different. I have added the table that is in the TravelDataPartial.csv file below as well. Please help figure out how to fix it so that I can get the above input!

In the answer, can you please modify the whole code so I can see where I went wrong?
