How do you calculate the distance a beam of light would travel in you hour?

To calculate the distance a beam of light travels in one hour, use the speed of light, which is approximately 299,792 kilometers per second (km/s). Multiply this speed by the number of seconds in an hour (3,600 seconds). The calculation is: 299,792 km/s × 3,600 s = about 1,079,252,848.8 kilometers. Thus, a beam of light travels roughly 1.08 billion kilometers in one hour.
