Light travels at a speed of 3.00 x 100 ^10 cm/s. What is the speed of light in kilometers/hour?

1.1 x km/h

Explanation:

Here we need to do two conversions- one from centimetres to kilometres and one from seconds to hours.

To get from cm to km- we divide by 100 000 since there are 100 000 cm in a km.

To get from seconds to hours we divide by 3600 since there are 3600 seconds in an hour

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

the answer is 303.15 or 303
