Answer:
Velocity = 0.5 m/s South (A)
Explanation:
You need to determine the average rate of velocity.
The equation you will use is velocity = displacement/time
The displacement is 30m South.
The time is 60 seconds.
Plug into the equation Velocity = 30m South/60 s
Velocity = 0.5 m/s South

Answer:
9.5 x 10^15 meters per year
Explanation:
So, you have:

We want the amount of meters light travels in one year. There are 3600 seconds in 1 hour, 24 hours in 1 day, and 365 days in a year. Using these conversion factors, we can set up some nice cancellations:

Seconds will cancel, hours will cancel, days will cancel. We have meters per year:
