60sec in a min/20=3*400m = 1200m/min*60(min per hr)= 72000m/h= 72km/h
Cycler's speed = 400/20 = 20 meters per second. Skier's speed = 1500/60 = 25 meters per second. The skier's average speed during his minute is 25% faster than the cyclist's average speed during his 20 seconds.
The cyclist is traveling faster as they cover 400m in 20 seconds, which means they are going at a speed of 20m/s. The skier covers 1500m in 1 minute, which is equivalent to 25m/s. Therefore, the skier is traveling faster.
You divide 400m by 20s to get: 400 m / 20 s = 20 m/s (which is a moderate speed for a vehicle)
100m in 20s = 300m in 60s = 1 minute so 300m x 60min = 18000m in 1hour Answer: 18 kilometres per hour

To calculate the speed of an object, you use the formula speed = distance/time. In this case, the object travels 100 meters in 20 seconds, so the speed would be 100 meters / 20 seconds = 5 meters per second. Therefore, the speed of the object is 5 m/s.
velocity is distance divided by time. (miles per hour, feet per sec, etc.) so the average speed of the ball is 10m/20s or .5 m/s
