Question

The speed of light is 1.86×10^5 miles per second.how many meters will light travel in 1.0 seconds

Answer 1

Einstein's theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second). ... The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.

Answer 2

Answer: $3.0\times 10^8m$

Explanation:

Speed is defined as the distance travelled per unit time.

$speed=\frac{distance}{time}$

Units of speed are inter convertible:

Given : speed = $1.86\times 10^5miles/sec$

That is in 1 second ,  light travels = $1.86\times 10^5miles$

Converting miles to meters:

1 mile = 1609.34 m

$1.86\times 10^5miles=\frac{1609.34}{1}\times 1.86\times 10^5=3.0\times 10^8m$

Thus speed of light will be $3.0\times 10^8$ meters.
