A. (individual, write in notebook)

1. The speed of light is 3. 0 x 10^8 m/s. How long does it take light to reach the earth from the sun, which is 1.5 x 10^11 m away?
2. An airplane takes off at 9:00 AM and flies at 300 km/h until 1:00 PM. At 1:00 PM its speed is increased to 400 km/h, and it maintains the speed until it lands at 3:30 PM. What is the plane’s average speed for the entire flight?
3. A car travels at 100 km/h for 2.0 h, at 60 km/h for the next 2.0 h, and finally at 80 km/h for 1.0 h. Find its average speed for the entire 5.0 h.
4. A Honda moving at 100 km/h is 80 km behind a Ford moving in the same direction at 60 km/h. How far does the Honda travel before it catches up with the Ford?
