In 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.
18/42 = 3/7 of an hour and 3/7*60*60 = 1543 seconds
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.
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
3.5 SECONDS
it is travelling 50km an hour
academic dishonesty
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.
Time = 18 / 46 = 0.391304348 hours = 1408.7 seconds (rounded).
533 times Wrong, 266.68 is the correct answer, A four stroke engine only fires each cylinder every other revolution
