пожалуйста решить уровнения и задачу6.300-h:12=5.470 уровнениязадача Две машины выехали одновременно навстречу друг другу из двух населёных пунктов,расстояние между которыми 560км.Одна машина проехала 235км и заглохла.Через сколько времени доедет до нее другая машина, если ее скорость 77 км/ч?

Answer 1

1)560-235=325км-проехала вторая машина. 2)325:77=через 4.22 часа-доедет вторая машина.

Answer 2

Equation Solution:

To solve the equation 6,300 - h:12 = 5,470, we can follow these steps:

1. Multiply both sides of the equation by 12 to eliminate the denominator: 12 * (6,300 - h:12) = 12 * 5,470 Simplifying, we get: 75,600 - h = 65,640

2. Next, isolate the variable 'h' by subtracting 75,600 from both sides of the equation: 75,600 - h - 75,600 = 65,640 - 75,600 Simplifying, we get: -h = -9,960

3. Finally, solve for 'h' by multiplying both sides of the equation by -1: -1 * (-h) = -1 * (-9,960) Simplifying, we get: h = 9,960

Therefore, the solution to the equation 6,300 - h:12 = 5,470 is h = 9,960.

Distance and Time Problem:

Now let's move on to the distance and time problem.

Two cars start simultaneously from two different towns and travel towards each other. The distance between the towns is 560 km. One car travels 235 km and then breaks down. We need to find out how long it will take for the other car to reach the broken-down car, given that its speed is 77 km/h.

To solve this problem, we can use the formula: time = distance / speed.

1. Calculate the time it takes for the second car to travel the remaining distance: Distance traveled by the second car = Total distance - Distance traveled by the first car Distance traveled by the second car = 560 km - 235 km = 325 km

Time taken by the second car = Distance traveled by the second car / Speed of the second car Time taken by the second car = 325 km / 77 km/h

2. Calculate the time in hours: Time taken by the second car = 4.22 hours (rounded to two decimal places)

Therefore, it will take approximately 4.22 hours for the second car to reach the broken-down car.
