Question

Помогите пожалусто небыл в школе уже 2 месяца.. Задача: мотоциклист в первый день ехал 3 часа со скоростью 60км/ч и столько же времени со скоростью 65км/ч.Скакой скоростью должен ехать мотоциклист во второй день, чтобы преодолеть оставшееся расстояние за 4 часа,если длина всего маршрута 655км?? ( помогите!!!!)

Answer 1

1) (3ч x 60км/ч) + ( 3ч x 65км/ч) = 275км - за 1 день                                          
2) 655км - 275км = 380км - осталось проехать
3) 380км : 4ч = 95км/ч - во второй день
Ответ : 95 км/ч 

Answer 2

Problem Analysis

The problem states that a motorcyclist traveled for 3 hours at a speed of 60 km/h and then traveled for the same amount of time at a speed of 65 km/h. The total distance of the route is 655 km. The task is to determine the speed at which the motorcyclist should travel on the second day to cover the remaining distance in 4 hours.

Solution

To solve this problem, we can use the formula: speed = distance / time.

Let's calculate the distance covered on the first day: - Speed = 60 km/h - Time = 3 hours - Distance = Speed * Time = 60 km/h * 3 hours = 180 km

The remaining distance to be covered on the second day is: - Total distance - Distance covered on the first day = 655 km - 180 km = 475 km

Now, we can calculate the speed required to cover the remaining distance in 4 hours: - Speed = Distance / Time = 475 km / 4 hours = 118.75 km/h

Therefore, the motorcyclist should travel at a speed of approximately 118.75 km/h on the second day to cover the remaining distance in 4 hours.

Answer

The motorcyclist should travel at a speed of approximately 118.75 km/h on the second day to cover the remaining distance in 4 hours.
