The correct answer is D. 4.68 x 108

To convert 130 kilometers per second to meters per hour, we need to multiply by the appropriate conversion factors. There are 1000 meters in a kilometer, and there are 3600 seconds in an hour. So, we have:

130 kilometers/second x (1000 meters/kilometer) x (3600 seconds/hour) 

= (130 x 1000 x 3600) meters/hour 

= 468000000 meters/hour

This can also be expressed in scientific notation as 4.68 x 10<sup>8</sup> meters per hour. Therefore, the correct answer is 4.68 x 10<sup>8</sup>.
