  • Any calculator can do that! Speed = Distance/Time Time = Distance/Speed For example, Polaris is about 430 light years away (2,527,810,000,000,000 miles) Lets say you were travelling at the speed of sound (769 mph) 2,527,810,000,000,000/769 ~= 3,287,140,000,000 ~= 374,994,892 yrs, 5 wks, 1 day, 12 hrs, 34 mins & 55.2 secs!
