Question

If I was traveling 76 mph on the highway, how many ly/s am I going?

Answer 1

the speed in light-year per second is 2.155 x 10⁻¹³ ly/s.

Step-by-step explanation:

Given;

speed in miles per hour (mph), v = 76 mph

1 mile = 1.701 x 10⁻¹³ light-year (ly)

1 hour = 60 s

The speed in light-year per second is calculated as follows;

`v = (76 \ miles)/(hour) * (1.701 * 10^(-13) \ ly)/(1 \ mile) * (1 \ hour)/(60 \ s) = 2.155 * 10^(-13) \ ly/s`

Therefore, the speed in light-year per second is 2.155 x 10⁻¹³ ly/s.
