Nettet9. apr. 2024 · There are 8766 hours in a year. Since, Distance = Speed x Time = s x t…. (1) Therefore, to find the distance of a light year, we need to multiply this speed by the number of hours in a year. Given, s = 1,079,252,849 km/h and t = 8766 hours. Putting the value of s and t in eq (1), we get: Distance = 1,079,252,849 x 8766.
