Question

Мотоциклу нужно проехать 800 км он проехал 500 км 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 11 ч?

Answer 1

800-500=300(км) - проехал по проселочной дороге
300:50= 6(ч) - по проселочной дороге ехал 6 часов
11-3= 8(ч) - Ехал по шоссе.
500:8= 62.5(км/ч) - скорость мотоциклиста по шоссе.

Answer 2

Calculation of Time and Speed for the Motorcycle Journey

To calculate the time and speed for the motorcycle journey, we need to consider the distance traveled on the highway and the distance traveled on the dirt road.

Given: - Total distance to be covered: 800 km - Distance traveled on the highway: 500 km - Speed on the dirt road: 50 km/h

To find the time spent on the dirt road, we can use the formula:

Time = Distance / Speed

1. Time spent on the dirt road: - Distance traveled on the dirt road = Total distance - Distance traveled on the highway = 800 km - 500 km = 300 km - Speed on the dirt road = 50 km/h - Time = 300 km / 50 km/h = 6 hours

Therefore, the motorcycle traveled for 6 hours on the dirt road.

To find the speed on the highway, we can use the formula:

Speed = Distance / Time

2. Speed on the highway: - Distance traveled on the highway = 500 km - Time spent on the entire journey = 11 hours - Time spent on the dirt road = 6 hours - Time spent on the highway = Total time - Time spent on the dirt road = 11 hours - 6 hours = 5 hours - Speed = 500 km / 5 hours = 100 km/h

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

Please note that the calculations are based on the given information and assumptions.
