What is the number of miles in a light-year, using (see picture) mi/s as the speed of light? I know the number of seconds in a year and 365 days will help but confused on how to put it in the equation. The text in the image is as follows:"1.86 x 10^5 mi/s"This notation is used to express a number in scientific notation. It signifies 1.86 multiplied by 10 to the power of 5 miles per second (mi/s). This is a way of representing large numbers more succinctly, commonly used in scientific and engineering contexts. For example, in decimal form, this would be equivalent to 186,000 miles per second, which is approximately the speed of light in a vacuum.

Question

What is the number of miles in a light-year, using (see picture) mi/s as the speed of light? I know the number of seconds in a year and 365 days will help but confused on how to put it in the equation.

The text in the image is as follows:

"1.86 x 10^5 mi/s"

This notation is used to express a number in scientific notation. It signifies 1.86 multiplied by 10 to the power of 5 miles per second (mi/s). This is a way of representing large numbers more succinctly, commonly used in scientific and engineering contexts. For example, in decimal form, this would be equivalent to 186,000 miles per second, which is approximately the speed of light in a vacuum.

Expert Solution

Step 1

The speed of the light in mi/s,

$c = 1.86 \times 10^{5} mi / s$

The time interval,

$t = 1 y e a r$
