- In astronomy, distances are often expressed in light-years. One light-year is the distance traveled by light in one year. If the distance to a star is 3.5 light-years, what is this distance in meters? (There are 365.25 days in one year.)Is it possible to estimate data while looking at the larger picture? Is it possible for a student to travel the globe without becoming broke?On day 5 of our trip we drove from Pompei to Vicenza in the north of Italy (440 miles, about 6 hours 28 minutes) – a long day of riding in the car. I was driving about 140 km/hour on the Autostrada (express toll road) in Italy. How fast was I driving in miles per hour
- What is the distance traveled?The ambulance car drove the distance 6,6 km. The first part of the way the car drove at a velocity 2,9 times higher than its average speed, and the second part of the way - at a velocity 3,6 times less than the average. Find the length of the first part of the path. Select the correct units of measurement in the field next to the answer.Can you give me a short summary about The Order of Time.
