Then subtract the numbers

Angel took 5/12 hours longer than Chris
In order to find the number of hours it takes to do the full rotation we separate into pieces the days, hours, and minutes and convert each of them separately.
using the conversion factor from days to hours we get that

then,

To complete add all the results together

It takes mercury 922.5 hours to complete a full rotation.
