Question

расстояние между городами 861км .из городов навстречу друг другу движутся машины одна из них прошла 3/7 всего расстояния адругая 2/7 на каком расстоянии друг от друга находятся машины

Answer 1

1) 861:7*3=369- проехала первая машина

2) 861:7*2=246- проехала вторая машина

3) 369+246-615 - проехали обе машины

4) 861-615=246 - расстояние друг от друга

 

 

 

 

 

 

Answer 2

Calculation of the Distance between the Cars

To calculate the distance between the two cars, we need to determine the distances each car has traveled.

Let's assume that the total distance between the cities is 861 km. According to the information provided, one car has traveled 3/7 of the total distance, while the other car has traveled 2/7 of the total distance.

To find the distance traveled by each car, we can use the following formulas:

Distance traveled by the first car = (3/7) * Total distance Distance traveled by the second car = (2/7) * Total distance

Substituting the given values, we can calculate the distances traveled by each car:

Distance traveled by the first car = (3/7) * 861 km Distance traveled by the second car = (2/7) * 861 km

Now, let's calculate the distances:

Distance traveled by the first car = (3/7) * 861 km = 369 km Distance traveled by the second car = (2/7) * 861 km = 246 km

Calculation of the Distance between the Cars

To find the distance between the two cars, we need to subtract the distance traveled by one car from the total distance traveled by both cars.

Let's denote the distance between the two cars as 'x' km.

According to the given information, the first car has traveled a distance of 369 km, and the second car has traveled a distance of 246 km.

To find the distance between the two cars, we can use the following equation:

Distance traveled by the first car + Distance traveled by the second car + Distance between the cars = Total distance

Substituting the given values, we can solve for the distance between the cars:

369 km + 246 km + x km = 861 km

Simplifying the equation:

615 km + x km = 861 km

Subtracting 615 km from both sides:

x km = 861 km - 615 km

x km = 246 km

Therefore, the two cars are currently 246 km apart from each other.

Please note that the calculations are based on the information provided and may vary depending on the actual distances traveled by the cars.
