The provided matrix represents the flight times between different cities. The rows represent the departing cities, and the columns represent the arriving cities. The elements of the matrix are the flight times in hours. Where there is no direct flight between two cities, a 0 is used to represent this in the matrix.
From the information provided:
- City 1 has flights to City 2, City 3, and City 5 with times 3.2, 3.5, and 5.4 hours, respectively.
- City 2 has flights to City 1, City 3, and City 4 with times 2.6, 1.8, and 2.1 hours, respectively.
- City 3 has a flight to City 4 with a time of 3.8 hours.
- City 4 has flights to City 1 and City 5 with times 6.8 and 7 hours, respectively.
- City 5 has a flight to City 4 with a time of 6.2 hours.
The correct checks for the matrix would be:
- [x] My matrix is the same size.
- [x] My matrix uses 0 to represent times to cities for which there was no flight.
- [x] My matrix has the same values for each corresponding element.
The provided matrix is correct based on the flight times given.
