which of the following is not true about the slope of a position-time graph. * O The slope The slope of a position-time graph equals change in position over the change in time. of a position-time graph equals the rise over the run. The slope thus equals the run over the rise. ()The slope thus equals the speed of the object. The slope of a position-time graph equals the rise over the run. is a straight line drawn through the set of plotted data points in a graph. O Line of arithmetic Line of best fit Line of symmetry Line of segmentation What is the speed of a bobsled whose distance-time graph indicates that it * traveled 300 m in 30 seconds? Speed = 11 m/s Speed = 10 m/s Speed = 30 m/s Speed = 1 m/s A train travels 200 kilometers in 4.0 hours and then 500 kilometers in 7 hours. What is its average speed? Average Speed = 121.43 m/B Average Speed = 658.00 m/s O Average Speed = 100.56 m/s Average Speed = 223.09 m/sWhich of the following graphs represents constant velocity in a negative * 1 point direction?
