Light travels at a speed of 3.00 * 10 to the power of 10 cm/sec. What is the speed of light in Kilometers per hour?
Go to www.google.com and type in
3 x 10^10 cm/sec to km/hour
To find the speed of light in kilometers per hour, we can first convert the speed from centimeters per second to kilometers per second, and then multiply by the number of seconds in an hour to convert it to kilometers per hour.
1 kilometer is equal to 100,000 centimeters, and 1 hour is equal to 3,600 seconds.
So, to convert the speed from centimeters per second to kilometers per second, we divide by 100,000:
3.00 * 10^10 cm/s / 100,000 = 3.00 * 10^5 km/s
Now, to convert kilometers per second to kilometers per hour, we multiply by 3,600:
3.00 * 10^5 km/s * 3,600 = 1.08 * 10^9 km/h
Therefore, the speed of light is approximately 1.08 * 10^9 kilometers per hour.
