1.)An object moves along a straight line. First it travels at a velocity of 12m/s for 5s and then continues at the same direction with 20m/s for 3s. What is its average speed? 2.)A car travels along the x-axis for 4s at an average velocity 10m/s and 2s with an average velocity 30m/s and finally 4s with an average velocity 25m/s. What is its average velocity across the whole path?
