Calculate the number of miles in a light year using (see picture for the equation) mi/s as the speed. Hint: The number of seconds in a year,365days,will be useful.

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
