∙ 13y agoIn the metric system, speed is measured in meters per second. So the average speed of the greyhound is 301 meters / 16.96 seconds = 17.747641509433962 m/s, approximately.

90 degrees. (360 degrees in a clockface, takes 60 seconds to cover all of them. So the second hand covers 6 degrees per second (360 divided by 60). Now multiply 6 degrees per second by 15 seconds - i.e 6 x 15 = 90
The car's average speed is 1/2 of (0 + 60) = 30 miles per hour.At 30 miles per hour, the car covers 396 feet in 9 seconds.
5SOS formed in 2011. Luke started posting covers on YouTube in 2011, and Mikey thought of starting a band so he, Luke and Calum formed 5 Seconds of Summer. In november/december 2011, Ashton joined the band.
No. Velocity = distance divided by time. Example: a body covers 100 metres distance in 10 seconds velocity = 100 / 10 = 10 m/s
It depends on what you mean by "how fast?" A bullet that covers 1000m in 3 seconds is travelling 333.33333333 meters per second.
Light. Since the speed of light is almost a million times the speed of sound (in air), it's hardly necessary to do lots of calculations to get this answer.Update: the number of seconds is actually irrelevant. To know how fast something goes, you only need the speed.
In 12 seconds, a car traveling at 87 miles per hour covers 211.2 feet. This is calculated by converting 87 miles per hour to feet per second, then multiplying by the time in seconds.
Constant speed and constant velocity
The heron is traveling 1 meter per second. The duck is traveling 12 meters per second. The duck is traveling faster.
1,668 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.
3.5 SECONDS
it is travelling 50km an hour

3 seconds of light in vacuum means a distance of 899377374 m. 100 seconds of sound in air of a temperature of 20°C or 68°F means a distance of 34300 m. Light covers a much longer distance.
If it covers 92 meters in one second one needs to work out how many 92 meters there are in 1 Kilometer and this will be the number of seconds required to travel 1 Kilometer. There are 1000 meters in a kilometer thus 1000/92 = 10.87 so it will take the train 10.87 seconds to travel 1 kilometer.
