Question

The speed of light is 3*10⁸ m/s (aka 300,000,000 meters per second). What is the speed of light in centimeters per second, kilometers per second, and miles per hour?

Answer 1

The speed of light is 3*10^8 m/s (or 300,000,000 meters per second). To find the speed of light in centimeters per second, multiply it by 100. To find the speed of light in kilometers per second, divide it by 1000. To find the speed of light in miles per hour, multiply it by 0.6214 and then by 3600.

Step-by-step explanation:

The speed of light is 3*108 m/s (or 300,000,000 meters per second). To find the speed of light in centimeters per second, we can use the conversion factor:

1 meter = 100 centimeters

So, the speed of light in centimeters per second is:

3*108 m/s * 100 cm/m = 3*1010 cm/s

To find the speed of light in kilometers per second, we can use the conversion factor:

1 kilometer = 1000 meters

So, the speed of light in kilometers per second is:

3*108 m/s / 1000 m/km = 3*105 km/s

To find the speed of light in miles per hour, we can use the conversion factors:

1 kilometer = 0.6214 miles

1 hour = 3600 seconds

So, the speed of light in miles per hour is:

3*108 m/s * (0.6214 miles/km) * (3600 s/hour) = 6.70692*108 mph
