WebFor example, the distance from Earth to the sun is about 93,000,000 miles. That's a pretty big number for the average person to comprehend. If the distance is expressed in light time, then the sun is about 8.33 minutes away from Earth. In other words, light from the sun takes 8.33 minutes to reach Earth. WebAs long as that is true, the basic technique works. Now, the distance from the earth to the sun varies from about .98 AU to 1.02 AU, so using 1 AU is at least 98% accurate for the length of the adjacent side. Since it is just a multiplicative factor, this translates to at least 98% accuracy for the final answer, regardless of distance. small stall layout for mehendiWeb6 views, 2 likes, 0 loves, 3 comments, 1 shares, Facebook Watch Videos from Zoom Into Books: He will be discussing his newest book, Twins highway advisory radio fdot
