19 kilometers is equal to about 11.81 miles.
2000m
70 m x 30 m = 2100 m^(2)
Answer: 159 m = 521.653 '
First of all, the speed of light is 3 x 108 meters per second, not 3 x 105.It will take 10 milliseconds for a ray of light to travel 3 x 106 meters at a speed of 3 x 108 meters per second.If the number in the question were correct, which they are not, the answer would be ten seconds.
1.00 km = 1,000 meters 2.00 km = 2,000 meters 3.00 km = 3,000 meters 4.00 km = 4,000 meters 4.26 km = 4,260 meters
1,000 meters = 1 km 2,000 meters = 2 km 3,000 meters = 3 km . . 40,000 meters = 40 km
1 km = 1,000 meters 2 km = 2,000 meters . . 10 km = 10,000 meters . . 20 km = 20,000 meters
1 km = 1,000 meters 2 km = 2,000 meters 3 km = 3,000 meters . . . 26 km = 26,000 meters
1 km = 1,000 meters 2 km = 2,000 meters 2.2 km = 2,200 meters
1 km = 1,000 meters 2 km = 2,000 meters 3 km = 3,000 meters . . 15 km = 15,000 meters
1.0 km = 1,000 meters 2.0 km = 2,000 meters 2.5 km = 2,500 meters
1 thousand meters = 1 km 2 thousand meters = 2 km . . 300 thousand meters = 300 km.
1.00 km = 1,000 meters 1.10 km = 1,100 meters 1.15 km = 1,150 meters
1 km = 1,000 meters 2 km = 2,000 meters 2.3 km = 2,300 meters
1 km is 1000 meters, so 1.93 km will be 1930 meters
1 km = 1000 meters 6.9 km= 6.9 * 1000 = 6900 meters
