How many meters are there in 19.0 light -year?

Answer 1

Having "A light-year is the distance light (speed = 2.998 108 m/s) travels in one year," you will then find how many seconds are in a year (31,556,926 seconds), multiply that number by 19 (given). Once you get how many seconds total in 19 years (599,581,594 seconds in 19 years) you will then multiple that number times the speed (2.998 108 m/s).

Final Answer: 1.798 x 1017
