Question

Convert 89.3 light years to m/s

Answer 1

Light has a constant speed of 300 million metres per second.
300 million metres per second x 60 seconds
= 18,000 million metres per minute

18,000 million meters per minute x 60 minutes
= 1,008,000 million metres per hour

1,008,000 million metres per hour x 24 hours
= 25,920,000 million metres per day

25,920,000 million metres per day x 365 days
= 9,460,800,000 million metres per year

And finally,

9,460,800,000 million metres per year x 89.3 years
= 844849440000 million metres in 89.3 years
