Question

Путешественники проплыли на яхте путь720км.Одну треть этого пути они плыли со скоростью 120км\ч,оставшееся расстояние плыли со скоростью 80 км\ч.Сколько времени были в пути туристы

Answer 1

720:3=240км он проплыл со скоростью 120 км/ч
720-240=480 км со скоростью 80км/ч
720:240=3 ч
480:80=6 ч
3+6=9 часов плыла яхта

Answer 2

Calculating the Travel Time of Tourists on a Yacht

To calculate the total time the tourists spent on their journey, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

Given: - Total distance traveled on the yacht: 720 km - Speed for the first one-third of the journey: 120 km/h - Speed for the remaining two-thirds of the journey: 80 km/h

Calculating the Time for the First One-Third of the Journey

Using the formula, the time taken for the first one-third of the journey can be calculated as: \[ \text{Time}_1 = \frac{720 \times \frac{1}{3}}{120} \]

Calculating the Time for the Remaining Two-Thirds of the Journey

Similarly, the time taken for the remaining two-thirds of the journey can be calculated as: \[ \text{Time}_2 = \frac{720 \times \frac{2}{3}}{80} \]

Total Time Spent on the Journey

The total time spent on the journey is the sum of the time taken for the first one-third and the time taken for the remaining two-thirds: \[ \text{Total Time} = \text{Time}_1 + \text{Time}_2 \]

Let's calculate the values using the given data.
