Light YearDate: 08/09/97 at 10:44:36 From: amanda Subject: Space How long (in miles) is a light year? I tried figuring out how to do this but I have no idea where to start. Date: 08/09/97 at 11:42:59 From: Doctor Anthony Subject: Re: Space Light travels approximately 186,000 miles per second, so to get the number of miles in a light year we must multiply by the number of seconds in a year. I shall take the year to be 365.25 days miles/sec days hrs min sec Light year = 186,000 x 365.25 x 24 x 60 x 60 = 5.8697136 x 10^12 miles i.e. 5.87 million million miles. -Doctor Anthony, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
