Will a bus and a car travel the same distance at a same speed in same time?
Yes. Time is a function of distance and speed, and independent of the method of achieving that speed over the distance. time = distance ÷ speed
What does straight line on a distance time graph tell you about the speed of an object?
It tells you that the speed of the object is not changing. The speed is represented by the slope in a distance vs. time graph, if slope doesn't change, speed doesn't.
Is distance a function of time?
Definitely. Distance is directly proportional to time, and the proportionality constant is called "speed".
If speed is a function of time or velocity is a function of time Then what should you do to calculate distance?
Distance equals speed multiplied by time. For example, speed is 72 km/h and time is 200 seconds or 200/3600=0,0(5) hours, so the distance traveled is 72*0,0(5)=4 kilometers.
What does the slop of a distance vs. time graph tell you?
The slope of a distance vs. time graph is a measure of the rate of change of the distance over time. It tells you the speed at which the distance is changing. If the slope is positive it means the distance is increasing with time. If the slope is negative it means the distance is decreasing with time. If the slope is zero it means the distance is not changing with time. Positive slope: distance is increasing with time. Negative slope: distance is decreasing with time. Zero slope: distance is not changing with time.The slope of the graph can be used to calculate the average speed of an object over a certain period of time. By taking the change in distance and dividing it by the change in time the average speed can be calculated.
