You have a common denominator which is time,
it is either stated in hours or days, hours is actually what we want, but it is days that we measure, we therefore need to calculate the total hours travelled, or we just measure hours and forget about the days, I do not see the purpose in a calculation of bringing in two different types (gone blank sorry, hours and days, meters and inches etc) for the same process variable
