(9368km)(1 min/500km)=18.736 minutes
. 
With your remainder of 368 (that is, 368/500 minutes), you can convert to seconds:
(368/500 minutes)(60 seconds/1 minute)=44 and 80/500 seconds=44.16 seconds
This makes a total of 18 minutes 44.16 seconds (same as 18.736 minutes).
.
500km/minute (a bit over 18,000 mph) is kind of fast for a bicycle.
