How many years is 300 light years away from earth?

Answer 1

the speed of light is 3 x 108 meters per second or m/s.

Light takes 1 secs to travel = 3 x 108 meters

1 year = 365 days = 365 x 24 hours (8760 hours) =8760 x 60 mins ( 525600 mins)

= 525600 x 60 secs (31536000 secs)= 31536000 seconds.

Total distance in meters travelled by light in 1 year = 31536000 x 3 x 108 meters 94608 x 1011 meters95 x 108 Kms

I have done the calculations multiple times based on the fact the the speed of light is 300,000 km/s and have come to the conclution that light travles 9,467,280,000,000 km in one year. This is the distance of a light year

Answer 2

Second of the year * speed of light. = 31536000*300000 = 9460800000000km are there in a light year.

Answer 3

25,000 light years = 1.46962495 × 1017 miles

Answer 4

A very long distance - about 17,609,140,800,000,000 miles.

Answer 5

Tricky, but at a guess. 146,965,634,333,010,000 miles or about 147 quadrillion miles

Answer 6

Light will travel 2.562211 x 10*15 km. in 6500 years.

Answer 7

1 light year = 5,878,600,000,000 (5.8786 x 1013) miles (rounded)

25,000 light years = 146,965,000,000,000,000 (1.46965 x 1017) miles (rounded)

Answer 8

About eight minutes.

Answer 9

671,080,888 mph
