MATLAB Understanding chacters as vectors.

The test suite workspace includes a character array variable named MarathonTime that stores a marathon runners race time in hours:minutes:seconds (HH:MM:SS) format. Write a script that uses this character array to compute the average mile pace time in decimal minutes and assigns the result to a single precision variable called MilePace. A marathon is 26.2 miles. So for an example calculation, if the total time is 03:45:16, the average mile pace time would be calculated as:
