Question

Мотоциклисту нужно проехать 800 км.Он проехал 500 км по шоссе,а остальной путь проделал по просёлочной дороге со скоростью 50 км\ч. Сколько времени он ехал по просёлочной дороге?С какой скоростью мотоциклист ехал по шоссе, если на весь путь он затратил 11 часов?

Answer 1

1) 800-500=300 (км) - по дороге
2) 300/50=6 (ч) - ехал по дороге
3) 11-6=5 (ч) по шоссе
4) 500/5=100 (км/ч) по шоссе
Ответ: 6 ч, 100 км/ч

Answer 2

Calculation of Time and Speed

To calculate the time the motorcyclist spent on the dirt road and the speed at which he traveled on the highway, we can use the given information.

The motorcyclist needs to travel a total distance of 800 km. He has already traveled 500 km on the highway, leaving 300 km to be covered on the dirt road.

Let's calculate the time spent on the dirt road first.

The motorcyclist traveled on the dirt road at a speed of 50 km/h. To find the time spent, we can divide the distance by the speed:

Time on dirt road = Distance / Speed = 300 km / 50 km/h = 6 hours

Therefore, the motorcyclist spent 6 hours on the dirt road.

Now, let's calculate the speed at which the motorcyclist traveled on the highway.

The total time taken for the entire journey is given as 11 hours. We already know that the motorcyclist spent 6 hours on the dirt road. Therefore, the remaining time was spent on the highway.

Time on highway = Total time - Time on dirt road = 11 hours - 6 hours = 5 hours

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

Speed on highway = Distance / Time = 500 km / 5 hours = 100 km/h

Therefore, the motorcyclist traveled on the highway at a speed of 100 km/h.

To summarize: - The motorcyclist spent 6 hours on the dirt road. - The motorcyclist traveled on the highway at a speed of 100 km/h.

Please note that the calculations are based on the given information and may not account for factors such as breaks or variations in speed during the journey.
