Question

2.2.Велосипедист движется равномерно из пункта А в пункт В, расстояние между которыми 10 км. Задайте формулой зависимость времени t, затраченного на этот путь от скорости. Начертите график, соответствующий данной функциональной зависимости

Answer 1

Ответ:

НУ смотри, путь равен произведению скорости тела на время, значит, из этой формулы, время равно отношению пути к скорости тела.

t=S/v, то есть t=10/v. У тебя получилась функция, только с другими переменными (сравни, y=10/x-обратная пропорциональность, график гипербола).

Строишь график, вместо х пишешь v, а вместо у пишешь t. Но стоишь гиперболу только в первой координатной четверти, так как время не может быть отрицательным.

Formula for the Time Spent on the Journey

To determine the formula for the time spent on the journey from point A to point B, we need to consider the relationship between speed, distance, and time. In this case, the cyclist is moving at a constant speed.

Let's assume that the speed of the cyclist is represented by v (in km/h), and the distance between point A and point B is 10 km. The formula for the time spent on the journey can be derived using the equation:

time = distance / speed

Substituting the given values, we get:

time = 10 km / v

Therefore, the formula for the time spent on the journey is t = 10 / v.

Graphical Representation

To visualize the relationship between the time spent on the journey and the speed of the cyclist, we can plot a graph. The x-axis represents the speed (v) in km/h, and the y-axis represents the time (t) in hours.

Since we have a formula for the time spent on the journey, we can substitute different values of speed (v) into the formula to calculate the corresponding time (t). By plotting these points on the graph, we can observe the relationship between speed and time.

Here is a graph that represents the relationship between the time spent on the journey and the speed of the cyclist:
