50m/min = 50*100 = 5,000cm/min = 5,000 / 60 = 83 1/3cm/sec.
Therefore 20cm/sec is slower.
2m/sec = 120m/min. 120>50. Therefore the answer is yes.
In vacuum . . . 299,792,458 meters (186,282 miles) per second. In material substances . . . somewhat slower, depending on the substance.
Very nearly 300,000,000 meters per second, in vacuum. A bit slower, but not much, in air.
No the 'second hand' of a clock has a higher velocity, it makes one rotation each minute, while the minute hand makes on rotation each hour and the hour hand makes one rotation every 12 hours.
Ripples on water travel slower than sound. Sound waves travel through air at a speed of roughly 343 meters per second, while ripples on water can travel at speeds as slow as a few meters per second, depending on factors like the depth of the water and the frequency of the ripples.
To do this you need to know:60 second in a minute60 minutes in an hour1609.344 meters in one mileNow first work out how far one would travel running at that speed in one minute, by finding how far you would have traveled in one second-100/9.7 = 10.30927835051546 meters /secondThen multiply by 60 to get distance traveled in one minute =10.30927835051546 * 60 = 618.5567010309278 meters / minute.Now multiply by 60 again to get the distance traveled in an hour618.5567010309278*60=37113.40206185567 meters / hourOK we now know that we would be running at a speed of 37113.40206185567 meters an hour. BUT we want the answer in miles an hour, so we have to divide this by the number of meters in a mile:37113.40206185567/1609.344=23.06 miles per hour.Compare this with the related answer for this question where the distance run was in Yards (which are shorter than meters - so you would be running slower)
In vacuum . . . 299,792,458 meters (186,282 miles) per second. Somewhat slower in material media, such as air, water, glass, jello, etc.
Zero. It is not getting any faster or slower
The unit of speed commonly used to express the speed of a tortoise is meters per second (m/s) or kilometers per hour (km/h). This unit measures the distance the tortoise travels in a given amount of time. The speed of a tortoise is typically much slower compared to other animals, such as cheetahs or horses.
Slower? less?
The speed of light in a vacuum is 300,000 kilometers per second (or 300 million meters per second). In a vacuum, light can ONLY move at that speed - neither faster, nor slower.
The speed of sound in the stratosphere is approximately 295 meters per second, which is slower than at sea level due to the lower temperature and density of the air at higher altitudes.
