1 hr = 3600 s 1000 m = 1 km speed = distance/time = 50m/10s = 5 m/s = 5 m/s x (3600 s/h) / (1000 m/km) = 18 km/h
18 minutes = 1,080 seconds (multiply minutes by 60 to get seconds).
360 feet per minute.
Since there are 3600 seconds in one hour, 12 seconds is 1/300 hour.To travel 18 meters in 12 seconds is the same average speed as traveling 5400 (300 x 18) meters in 1 hour, or 54 km per hour.
Average speed = 10 meters per 2 seconds.Other ways of stating it:-- 5 meters per second-- 18 kilometers per hour
