The distance of galaxy from the earth isassuming the speed of light to be find the time taken by light to travel this distance​

Answers (1)

The distance of galaxy from the earth = 5.6 \times {10}^{25} ​
 the speed of light =  3 \times 10^{8} \ m/s

 time taken by light to travel this distance​ = \frac{distance}{speed}=\frac{5.6\times10^{25}}{3\times 10^8}=3 \times 10^{16} m
