Question

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

Answer 1

1)800-500=300(км) ехал по проселочной дороге

2)300/50=6(ч)ехал по проселочной дороге

3) 11-6=5(ч)ехал по шоссе

4)500/5=100(км\ч) скорость по шоссе

ответ: 100км\ч

Answer 2

Calculating Time and Speed for the Motorcycle Journey

To calculate the time the motorcyclist spent on the dirt road and the speed on the highway, we can use the following information:

- The total distance the motorcyclist needs to travel is 800 km. - The motorcyclist has already traveled 500 km on the highway. - The motorcyclist traveled the remaining distance on a dirt road at a speed of 50 km/h. - The total time taken for the entire journey was 11 hours.

Time Spent on the Dirt Road

To find out how much time the motorcyclist spent on the dirt road, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

Using this formula, we can calculate the time spent on the dirt road: \[ \text{Time} = \frac{800 - 500}{50} \]

\[ \text{Time} = \frac{300}{50} \]

\[ \text{Time} = 6 \text{ hours} \]

The motorcyclist spent 6 hours on the dirt road.

Speed on the Highway

To find out the speed at which the motorcyclist traveled on the highway, we can use the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

Using this formula, we can calculate the speed on the highway: \[ \text{Speed} = \frac{500}{11 - 6} \]

\[ \text{Speed} = \frac{500}{5} \]

\[ \text{Speed} = 100 \text{ km/h} \]

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