Question

К приезду начальника на станцию обычно присылают машину. Приехал он однажды на час раньше, пошёл пешком и, встретив посланную за ним машину, прибыл с ней на место на 10 мин раньше обычного срока. Во сколько раз скорость машины больше скорости начальника? помогите пожалуйста

Answer 1

T = время езды машины в один конец
t-5 = время езды машины до встречи с начальником
V = скорсть езды машины
5V = расстояние которое прошел начальник
60 - t = время ходьбы начальника до того как машина выехала в его направлении
v = скорость ходьбы начальника
(60 - t) + (t-5) = 55время ходьбы начальника
55v = 5V = расстояние которое прошёл начальник
скорость машины в 11 раз больше

Calculation of the Car's Speed Compared to the Chief's Speed

To determine the ratio of the car's speed to the chief's speed, we can use the information provided in the question.

According to the question, the chief arrived at the destination 10 minutes earlier than usual. This means that the chief's walking speed is such that it takes him 10 minutes longer to reach the destination compared to when he travels by car.

Let's assume the usual travel time for the chief by car is T minutes. Therefore, the chief's walking time would be T + 10 minutes.

Now, let's consider the time it took for the car to reach the destination. The car started at the same time as the chief, but the chief arrived 10 minutes earlier. This means that the car took T minutes to reach the destination.

To calculate the ratio of the car's speed to the chief's speed, we can use the formula:

Car's speed / Chief's speed = Car's travel time / Chief's travel time

Substituting the values we have:

Car's speed / Chief's speed = T minutes / (T + 10) minutes

Unfortunately, the question does not provide the exact values for the travel time or the time it takes for the chief to walk. Therefore, we cannot determine the exact ratio of the car's speed to the chief's speed without this information.
