Question

Срочно!! Расстояние между городами А и В равно 760 км. Из города А в город В со скоростью 55 км/ч выехал первый автомобиль, а через два часа после этого навстречу ему из города В выехал со скоростью 75 км/ч второй автомобиль. На каком расстоянии от города А авто встретятся? Ответ дайте в километрах -Ну позязя :(

Answer 1

Ответ:

Пошаговое объяснение:я бы помог но незнаю

Answer 2

Ответ:

385 км

Пошаговое объяснение:

1) 55 * 2 =110 ( км ) находилось авто 1 , когда выехало 2 авто

2) 760 -110= 650 (км) стало расстояние

3) 55 * 5 = 275 ( км ) проехало 1 авто после выхода 2 авто

4) 275+ 110 = 385 ( км ) проехал 1 автомобиль

                                              ПРОВЕРКА

5)75* 5= 375 (км) проехало 2 авто

6) 375+ 385= 760 (КМ ) начальное расстояние

Ответ : 385 км

Answer 3

Calculation of Meeting Point Distance

To find the distance at which the two cars will meet, we need to calculate the time it takes for the second car to catch up to the first car.

Let's break down the problem:

- The distance between city A and city B is 760 km. - The first car travels from city A to city B at a speed of 55 km/h. - The second car starts two hours later and travels from city B to city A at a speed of 75 km/h.

To calculate the meeting point distance, we can use the formula:

Meeting Point Distance = (Speed of the First Car * Time of the Second Car) + (Speed of the Second Car * Time of the First Car)

Let's calculate the meeting point distance step by step:

1. Calculate the time it takes for the second car to catch up to the first car: - The second car starts two hours later than the first car, so the time of the second car is the time of the first car minus two hours. - Time of the Second Car = Time of the First Car - 2 hours

2. Calculate the meeting point distance using the formula: - Meeting Point Distance = (55 km/h * Time of the Second Car) + (75 km/h * Time of the First Car)

Let's calculate the meeting point distance using the given information:

1. Calculate the time it takes for the second car to catch up to the first car: - Time of the First Car = Distance / Speed of the First Car = 760 km / 55 km/h = 13.818 hours - Time of the Second Car = Time of the First Car - 2 hours = 13.818 hours - 2 hours = 11.818 hours

2. Calculate the meeting point distance: - Meeting Point Distance = (55 km/h * 11.818 hours) + (75 km/h * 13.818 hours) = 649.99 km

Therefore, the two cars will meet at a distance of approximately 650 km from city A.

Please note that the calculated meeting point distance is an approximation due to rounding the decimal places in the calculations.
