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.)
Light travels at a speed of about 186,282 miles per second in a vacuum.
The definition of the speed of light in a vacuum is 300,000,000 meters/sec, or 186,000 miles/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.
The same speed as all electromagnetic waves. The speed of light. 186,000 miles per second. 300,000 km/sec.
Approx 3,00,000 km/sec and in hours=1,079,256,848,800 meters (670,615,200 miles) per hour.
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.
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.
Yes, electromagnetic waves, including light, travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second).
Light can travel 5,869,713,600,000 miles in one year's time.
The speed of light in a vacuum is approximately 299,792,458 meters per second.
Oh boy ! (186,282 mi/sec) x (3,600 sec/hr) x (1 AU / 93,000,000 mi) = (186,282 x 3,600 / 93,000,000) (mi - sec - AU / sec - hr - mi) = 7.211 AU/hr (rounded) Now what are you going to do with that number ??
