Question

Туристы Плыли на катере путь 720 км Одну треть пути они плыли со скоростью 120 километров в час оставшееся расстояние плыли скоростью 80 км в час сколько времени были в пути туристы

Answer 1

720:3=240 (км) плыли со скоростью 120 км/ч
720-240=480 (км) со скоростью 80 км/ч
240:120=2 (ч) плыли первые 240 км
480:80=6 (ч) плыли оставшийся путь
2+6=8 (ч)
Ответ: туристы были в пути 8 часов

Answer 2

Calculation of the Travel Time

To calculate the travel time of the tourists, we need to determine the time taken for each segment of the journey and then add them together.

1. First Segment: The tourists traveled one-third of the total distance at a speed of 120 km/h. - Distance covered in the first segment: 720 km * (1/3) = 240 km - Speed in the first segment: 120 km/h - Time taken in the first segment: Distance / Speed = 240 km / 120 km/h = 2 hours

2. Second Segment: The remaining distance is two-thirds of the total distance and was covered at a speed of 80 km/h. - Distance covered in the second segment: 720 km * (2/3) = 480 km - Speed in the second segment: 80 km/h - Time taken in the second segment: Distance / Speed = 480 km / 80 km/h = 6 hours

3. Total Travel Time: To find the total travel time, we add the time taken for each segment. - Total travel time = Time taken in the first segment + Time taken in the second segment = 2 hours + 6 hours = 8 hours

Therefore, the tourists were in travel for 8 hours.
