Question

The graph below describes the dependence of the time traveled from point A to point B, on the speed at which the traveling occurs. With the help of the graph answer the following questions: 2 4 t, h 6 8 10 12 14 16 200 400 600 800 v, km/h How much time is necessary for traveling between points A and B, when the speed is 800 km/hour; 250 km/hour; 120 km/hour?

Answer 1

To find the travel time at different speeds, we apply the formula v = d/t, but without the distance between points A and B or the actual graph, we can only explain the method and not provide specific times.

Step-by-step explanation:

To determine the time necessary for traveling between points A and B at different speeds, we use the relationship v = d/t, where v is velocity, d is distance, and t is time. If the graph provided was actually depicting this relationship, we could infer the necessary time values. However, it seems there is no specific graph provided in this question. Therefore, without the actual graph, we cannot give a precise answer. Still, we can apply the formula by assuming we know the distance between points A and B. If the distance was given, and using the velocity values asked in the question (800 km/hour, 250 km/hour, 120 km/hour), we'd be able to calculate time as t = d/v.

For example, suppose the distance between points A and B is 400 km:

• For 800 km/h, the time would be t = 400 km / 800 km/h = 0.5 hours.
• For 250 km/h, the time would be t = 400 km / 250 km/h = 1.6 hours.
• For 120 km/h, the time would be t = 400 km / 120 km/h = 3.33 hours.

Without the graph or the actual distance, we can provide the method for calculation but not the specific times.
