I also do sprints for my track team. I think the best way to do this would be to double your time and add one second. the other way is just have someone time you in a 60m dash. shouldn't take longer than 9 seconds give or take ;)

The GCF of 12m, 15m and 30m is 3m.
30m (meters) is 98.425 feet or 16.4 fathoms.

Day traders will usually use 1m, 5m, 15m or 30m time frames. Which time frame to choose is depends on the trader's character, an aggressive trader will probably use the 1m and 5m, a more serene trader will probably use the 15m or 30m.
30m = 3000cm, so there are 1000 lots of 3cm in 30m
50m/30m = 50/30 = 5/3
120m^3/30m^2 = 4 meters
