Astronomy Hw Help.....Please?

Question

How do I convert 1 light second into kilometers/miles?? I have a few hw questions like this so if anyone knows the formula...Help is appreciated.

Answer 1

Tina's wrong, that doesn't help here. A light second is 300,000 km per second. So just convert km to miles by multiplying 300,000 by 0.621371192 . There you go. And it is about 186,000 miles per second.

Answer 2

speed = distance / time

you know the speed. you know the time. plug in the numbers and work out the distance.

Answer 3

One light second is the distance the speed of light travels in 1 second.

And the speed of light is 299792.458 km/s.

D=VT where D is Distance, V is Velocity, and T is Time

D=(299792.458km/s)*(1second)

D=299792.458 km

Answer 4

Think about it. A light second is the distance traveled by a ray of light in one second. Light travels at a speed of 3x10^8 meters per second. That means that in one second it travels 3x10^8 meters, or 3x10^5 kilometers, or 186 411.358 miles.

Answer 5

light travels 300,000 kilometers per second.

mile can be converted into kilometers by multiplyimg with 1.601

Hope this along with Tina's answer will solve your problems!
