You have miles per second and seconds.
To get an answer in miles you need to eliminate the seconds unit. What do you know about fractions?
One light-year is the distance light travels in a 365-day year. The speed of light is about 186,282.4 miles per second. How long is a 2 light-year period (in miles). Express your answer in scientific notation.
1 mile = 5280 feet
1 hour = 60 minutes = 3600 seconds
1 day = 24 hours * 3600 seconds = 86,400 seconds
Then 86,400 seconds * 365 days = 31,536,000 seconds
I don't know how to use this information to answer the math question.
you have number of second per year (365.25 or 365 depending of precision that you need)
and you have speed of light in miles per second ....
than for one ore two or ... any number of years ... ( you just need number of seconds ) and multiply it with that speed of light .... and you will get in miles distance that light goes for that time
You have the velocity and time, so just multiply them together to solve for the distance travelled.
So in 2 years, light travels miles (assuming it is in a vacuum, and there are 365 days in a year)
Or to be more accurate, assuming there are 365.25 days in a year, light travels miles
