A lightyear is a unit of length equal to the distance that light travels in 1 year. What is 1

lightyear expressed in units of meters? The speed of light is 3.00 × 108 m/s.

The speed is 3.00E8 m/s so it will travel in 1 year how far?

There are 60 seconds in minute.
There are 60 minutes in 1 hour.
There are 24 hours in a day.
There are 365 days in a year.
Put all of that together. You know the factor is set up correctly if the unit you don't want to keep cancels and leaves the unit you want to keep. The first factor is
60 sec/min.
3.00E8 m/s x (60 sec/min). Note the sec cancel and leaves you with 3.00E8m/min. The next factor will convert to hours, the next to days, the next to years.

To find out how many meters are in 1 lightyear, we need to determine how far light can travel in one year.

We are given that the speed of light is 3.00 × 10^8 m/s. This means that light can travel 3.00 × 10^8 meters in one second.

Next, we need to determine how many seconds are in a year. There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day. Additionally, there are 365 days in a year (ignoring leap years for simplicity). So, to find the number of seconds in a year, we can calculate:

60 seconds/minute * 60 minutes/hour * 24 hours/day * 365 days/year = 31,536,000 seconds/year

Now we can find the distance light can travel in one year:

Distance = Speed * Time = (3.00 × 10^8 m/s) * (31,536,000 s/year)
Distance = 9.46 × 10^15 meters

Therefore, 1 lightyear is equal to approximately 9.46 × 10^15 meters.
