Answer 1

Answer:

One lightyear is the distance light travels in one year. Light travels (in round figures) at 300,000 km/sec, and there are 31,536,000 seconds in one year (60 x 60 x 24 x 365). Thus, one lightyear is equivalent to 31,536,000 x 300,000 = 9,460,800,000,000 km. Four lightyears are four times this amount, i.e. 37,843,200,000,000 km, or 37.8 tera kilometres (again, in round figures).
