Help with some python homework...

So, this is what I came up with. It works, which is good but it’s a little different from a few things you guys had mentioned. For one, I got the correct time by calculating the number of time run and converting that into seconds then back out to hr:mn:sc. I didn’t calculate from midnight. That seemed more complicated to me because I’d have to figure the number of seconds from midnight to 6:52am then do the calculations for number of seconds run until I got home, then I got kind of lost. Also, before I forget what is the difference between / and //? I remember something about floor division? Not sure what that means though. Is it like a % where it gives the remainder after dividing? Thanks again. Code below. Also, I think I found out through a little trial and error that I had two different hours, mins, and sec so I had to use one uppercase and one lower case. Is that frowned upon? And should I have come up with a different name instead?
SECONDS = 1
MINUTES = 60 * SECONDS
HOURS = 60 * MINUTES
time_left_house = 6 * HOURS + 52 * MINUTES
miles_run_easy_pace = 2 * (8 * MINUTES + 15 * SECONDS)
miles_run_fast_pace = 3 * (7 * MINUTES + 12 * SECONDS)
time_returned_home = miles_run_easy_pace + miles_run_fast_pace + time_left_house
hours = time_returned_home // HOURS
part_hour = time_returned_home % HOURS
minutes = part_hour // MINUTES
seconds = part_hour % MINUTES
print "Time returned home:", hours,":", minutes,":", seconds,”am"
