Question

Две машины выехали одновременно навстречу друг другу из 2-х населенных пунктов, расстояние между которыми 560 км. Одна машина проехала 235 км и заглохла. Через сколько времени доедет до нее другая машина, если ее скорость 77 км/ч

Answer 1

1)560-235=325(км.) через столько доедет 2 машина до 1.
2)325:77=40.45.(мин.)
3)40+45=85(мин.)
4)85мин=1ч.45 мин.
Ответ:через 1ч.45мин.доедет 2 машина до 1

Answer 2

Problem Analysis

We have two cars that start simultaneously from two different towns and are traveling towards each other. The distance between the towns is 560 km. One car travels 235 km and then breaks down. We need to calculate how long it will take for the other car to reach the broken-down car.

Solution

To solve this problem, we can use the formula: time = distance / speed. We know the distance traveled by the first car (235 km) and the speed of the second car (77 km/h). We can calculate the time it takes for the second car to reach the broken-down car.

Let's calculate the time:

1. Calculate the remaining distance between the two cars: - Remaining distance = Total distance - Distance traveled by the first car - Remaining distance = 560 km - 235 km = 325 km

2. Calculate the time it takes for the second car to cover the remaining distance: - Time = Remaining distance / Speed of the second car - Time = 325 km / 77 km/h

Using the formula, we can calculate the time it takes for the second car to reach the broken-down car.

Calculation

Let's calculate the time it takes for the second car to reach the broken-down car:

1. Remaining distance = 325 km 2. Speed of the second car = 77 km/h

Time = Remaining distance / Speed of the second car Time = 325 km / 77 km/h

Calculating the above expression, we find that it takes approximately 4.22 hours for the second car to reach the broken-down car.

Answer

The second car will reach the broken-down car in approximately 4.22 hours.

Please note that this calculation assumes a constant speed for the second car and does not take into account any delays or changes in speed during the journey.
