Question

Расстояние от а до в равно 180км.Турист прошёл 3/8 пути, а затем ехал на велосипеде 12км/ч.сколько времени нужно на второй участок пути

Answer 1

Второй участок пути равен 1-3/8=5/8 части всего пути и составляет 180*5/8=112.5 км. На то, чтобы проехать его на велосипеде, туристу нужно 112.5/12=9.375 часа.

Answer 2

Problem Analysis

We are given that the distance from point A to point B is 180 km. The tourist has already traveled 3/8 of the total distance and is now traveling on a bicycle at a speed of 12 km/h. We need to find out how much time it will take for the tourist to complete the second part of the journey.

Solution

To find the time it will take for the tourist to complete the second part of the journey, we need to calculate the remaining distance and divide it by the speed of the bicycle.

Let's calculate the remaining distance: - The tourist has already traveled 3/8 of the total distance, which is (3/8) * 180 km = 67.5 km. - Therefore, the remaining distance is 180 km - 67.5 km = 112.5 km.

Now, let's calculate the time it will take to cover the remaining distance: - The speed of the bicycle is given as 12 km/h. - We can use the formula: time = distance / speed. - Substituting the values, we get: time = 112.5 km / 12 km/h = 9.375 hours.

Therefore, it will take approximately 9.375 hours for the tourist to complete the second part of the journey.

Answer

The tourist will need approximately 9.375 hours to complete the second part of the journey.
