## Light Speed Distance Formula

The following formula is used to calculate the Light Speed Distance.

**LSD = LS * T**

- Where LSD is the Light Speed Distance (m)
- T is the total time of travel at light speed (s)
- LS is the speed of light (299,792,458 m/s)

## How to Calculate Light Speed Distance?

The following example problems outline how to calculate Light Speed Distance.

Example Problem #1:

- First, determine the total time of travel at light speed (s).
- The total time of travel at light speed (s) is given as: 3s.

- Finally, calculate the Light Speed Distance using the equation above:

LSD = LS * T

The values given above are inserted into the equation below and the solution is calculated:

LSD = 299,792,458 * 3 = 899377374 (m)

Example Problem #2:** **

For this problem, the variables needed are provided below:

total time of travel at light speed (s) = 6

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

LSD = LS * T** = ?**
