what is half of speed of light? (3x10^8m/s)
3/2 = 1.5
1.5 * 10^8 meters/second
are you kidding? What is the problem?
the problem is this
If the speed of light is 3x10^8m/s and the distance around the earth is 4.5x10^4 km and a plane could travel at half a speed of light, how long would it take for the plane to fly around the earth twice?

To find half the speed of light, you simply divide the speed of light by 2.
The speed of light is approximately 3 x 10^8 meters per second. To find half of this value, you can divide by 2:
(3 x 10^8 m/s) / 2 = 1.5 x 10^8 m/s
So, half the speed of light is approximately 1.5 x 10^8 meters per second.
