Light travels at a speed of 3.00 times 10^10 cm/s. What is the speed of light in kilometers/hour?
u stupid
To find the speed of light in kilometers/hour, we need to convert the units from centimeters/second to kilometers/hour.
1 kilometer = 100,000 centimeters
1 hour = 3600 seconds
First, let's convert the speed of light from centimeters/second to kilometers/second:
Speed (km/s) = Speed (cm/s) / 100,000
Speed (km/s) = 3.00 x 10^10 cm/s / 100,000
Speed (km/s) = 3.00 x 10^5 km/s
Next, let's convert the speed from kilometers/second to kilometers/hour:
Speed (km/h) = Speed (km/s) x 3600
Speed (km/h) = 3.00 x 10^5 km/s x 3600
Speed (km/h) = 1.08 x 10^9 km/h
Therefore, the speed of light is approximately 1.08 x 10^9 kilometers per hour.
first multiply by 10^-2 to get meters instead of centimeters so
3 * 10^8 m/s * 1 km/10^3m * 3600 s/hr
= 10800 * 10^5 = 1.08 * 10^9 km/hr
or type
3*10^8 m/s = km/hr
Into a Google search box
Google it.
Go to Google, type in "3.00E10 cm/s to km/hr" without the quotation marks and hit the enter button.
