#1. A car moving at the rate of 65 miles per hour passes a truck moving in the same direction at 38 miles per hour. The speed of the car from the truck's frame of reference is 27 miles per hour.
#2. The X-43 is the fastest aircraft ever. It flew a distance of 3,961 km from Los Angeles to New York at the speed of 11,265 km/h. It took the X-43 (3,961 km) / (11,265 km/h) = 0.352 hour, or 21min 5.8sec to fly that distance?
#3. A mail carrier walked six blocks to the north one block to the east , and then six blocks to the south. After these three moves, the mail carrier's displacement is one block to the East.
