  • 1. How long would it take a car to return to its starting place if it traveled 180 km at an average speed of 90 km/hr and returned to its starting place along the same straight line path? (neglect the time that the car takes to turn around)

    		  
    2.      If a moving object travels north for a distance of 100 m in 20 sec, what is its velocity?  
    3. What is the speed of a jet plane that travels 528 meters in 4 seconds?

    6. The space shuttle Endeavor is launched to altitude of 500 km above the surface of
    the earth. The shuttle travels at an average rate of 700 m/s. How long will it take for
    Endeavor to reach its orbit?    		  
    7. How long will your trip take (in hours) if you travel 350 km at an average speed of
    80 km/hr?
