Question

Весь путь автомобиля составил 465 км на первый участок пути по шоссе автомобиль затратил 3 часа на второй По проселочной дороге 5 Найдите скорость автомобиля на каждом участке пути если известно что на проселочной дороге его скорость была на 27 км ч меньше чем на шоссе

Answer 1

 27*3= 81(км) - путь по шоссе
465-81= 384(км) - оставшийся путь
384:(5+3)= 48(км/ч) - V 1 автомобиля
48+27= 75(км/ч) - V 2 автомобиля
Ответ: 48 км/ч; 75 км/ч
Это легко

Answer 2

Calculation of Speed on Each Segment of the Journey

To find the speed of the car on each segment of the journey, we need to divide the distance traveled on each segment by the time taken on that segment.

Given: - Total distance traveled: 465 km - Time taken on the first segment (highway): 3 hours - Time taken on the second segment (dirt road): 5 hours - Speed on the dirt road is 27 km/h less than on the highway

Let's calculate the speed on each segment:

1. Speed on the highway segment:

To find the speed on the highway segment, we divide the distance traveled on the highway by the time taken on the highway:

Speed on the highway = Distance on the highway / Time on the highway

Distance on the highway = Total distance - Distance on the dirt road = 465 km - Distance on the dirt road

Time on the highway = 3 hours

2. Speed on the dirt road segment:

The speed on the dirt road is 27 km/h less than on the highway. So, we subtract 27 km/h from the speed on the highway to get the speed on the dirt road.

Speed on the dirt road = Speed on the highway - 27 km/h

Now, let's calculate the distance on the dirt road:

Distance on the dirt road = Total distance - Distance on the highway = 465 km - Distance on the highway

Time on the dirt road = 5 hours

Calculation Steps:

1. Calculate the distance on the dirt road: - Distance on the dirt road = Total distance - Distance on the highway - Distance on the dirt road = 465 km - Distance on the highway

2. Calculate the speed on the dirt road: - Speed on the dirt road = Speed on the highway - 27 km/h

3. Calculate the speed on the highway: - Speed on the highway = Distance on the highway / Time on the highway

Let's calculate the values step by step.

Calculation:

Step 1: Calculate the distance on the dirt road: - Distance on the dirt road = Total distance - Distance on the highway - Distance on the dirt road = 465 km - Distance on the highway

Step 2: Calculate the speed on the dirt road: - Speed on the dirt road = Speed on the highway - 27 km/h

Step 3: Calculate the speed on the highway: - Speed on the highway = Distance on the highway / Time on the highway

Now, let's calculate the values step by step.

Step 1: Calculate the distance on the dirt road:

- Distance on the dirt road = Total distance - Distance on the highway - Distance on the dirt road = 465 km - Distance on the highway

Step 2: Calculate the speed on the dirt road:

- Speed on the dirt road = Speed on the highway - 27 km/h

Step 3: Calculate the speed on the highway:

- Speed on the highway = Distance on the highway / Time on the highway

To find the values of Distance on the highway and Distance on the dirt road, we need more information. Could you please provide the distance traveled on the highway and the dirt road separately?
