Answer:
1.07928 x 10⁹ km
Step-by-step explanation:
How many seconds are there in an hour?
60 * 60 = 3600
If it takes light one second to travel 2.998 x 10⁸ m , then much distance would teh light cover in 3600 seconds ?
2.998 x 10⁸ m * 3600 = 1.07928 x 1012 m
1000 m = 1 km
Therefore; 1.07928 x 10¹² m / 1000 m
= 1.07928 x 10⁹ km
