1) multiply 30000000000 with 3600 ( for per second to per hour conversion )
2) divide by 100000 for cm to kilometers conversion.

300,000 k,/sec i think so because 1 kilo meter is equal to 1000 meters and 1 meter is 100 centimeters so just erase 5 zero's from behind to get kilometers. i mean just devide it.

1,080,000,000 kilometers per hour
Light travels at 300,000,000 m/s, approximatley
Divide by 1000 to get kilometers
Multiply by 3600 to get by hour
the exact answer is 1,079,252,848.8 km/h

if my math is correct it is 1.07941157938944E9 kilometers per hour
light travels at 186,282 miles per second , multiple that by 60, to give you 11176920 miles per minute.
multiple that by 60 to give you 670715260 miles per hour
One mile is equal to 1.609344 kilometers
after all this math as i said you get
1.07941157938944E9 kilometers per hour
if this is wrong,,oh well i tried

30,000,000,000 cm/sec * (1km / 100,000 cm) * (3600 sec / 1 hr)
That's how to convert it.
