186,000 miles per second
Miles per hour Kilometer per hour Ft per sec
Divided speed by 4, then add 2I.E 40km is 12m a sec
Answer 7.6 mph Explanation: 3.4 meters = 0.00211266205 miles So the speed is about .002 miles/second and there are 3600 seconds in a hours. so that is .002x3600=7.2 miles per hour. Now if we use .00211 then we have 7.6 which is a better estimate. 3.4 meters/sec which is about 7.6 mph.
100 miles per hour = 100*1.609344 kilometres per hour = 160.9344 kilometres per hour = 160.9344/3600 kilometres per second = 0.0447 km per sec (approx).
184 yds in 3 min. 4 sec = 184 yds in 184 sec. = 1 yard per second (or 3 ft per sec.)
The definition of the speed of light in a vacuum is 300,000,000 meters/sec, or 186,000 miles/sec.
The same speed as all electromagnetic waves. The speed of light. 186,000 miles per second. 300,000 km/sec.
The square of the speed of light is 89,880,000,000,000,000 meters2 per second2, or 34,700,000,000 miles2 per second2 "How fast" is meaningless, because the square of a speed isn't a speed any more.
Approx 3,00,000 km/sec and in hours=1,079,256,848,800 meters (670,615,200 miles) per hour.
1mile = 1.609 km Speed of light in kms-1 = 300000 kms-1 Speed of light in miles per sec = 300000/1.609 ms-1 = 186451.21 mps In mph, speed of light = 671224362.958 mph
about 300,000 km per sec.
Answer In vacuum, the speed of light is 186,282.397 miles per second. Answer The speed of light is not a constant. It is slowing down. zthere have been several experiments that prove that light is slowing down.186,282.4 miles per second.
17987547480m/min -> speed of light per minute 299792458m/s -> speed of light per sec or light speed
The speed of light in vacuo is called c. It is defined as 299 792 458 m s-1.In old anglo-saxon measure it is approximately 186,000 miles per sec.
Electromagnetic radiation, such as light, travels at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is considered to be the maximum speed limit in the universe.
1mile = 1.609 km Speed of light in kms-1 = 300000 kms-1 Speed of light in miles per sec = 300000/1.609 ms-1 = 186451.21 ms-1 In mph, speed of light = 671224362.958 mph
Acceleration = velocity change / time A = (v2 - v1) / t A = (15 - 5) / 6 = 10 / 6 = 1.66667 miles per sec2 (miles per sec. per sec.)
