Question

расстояние от а до в 180 км/ч.турист прошел 3/5 пути пешком,а затем ехал на велосипеде со скоростью 12км/ч.сколько времени понадибится туристу преодолеть второй отрезок. пути

Answer 1

1) 180 : 5 * 3 = 108 км турист прошел пешком
2) 108 : 12 = 9 час
Ответ: Второй участок пути турист преодолел за 9 часов

Answer 2

Calculating Time Needed to Cover the Second Distance Segment

To calculate the time needed for the tourist to cover the second distance segment, we can follow these steps:

1. Calculate the Total Distance and Distance Covered on Foot: - The total distance from point A to point B is 180 km. - The tourist covered 3/5 of the total distance on foot.

2. Calculate the Remaining Distance: - To find the remaining distance, we can use the fact that the tourist covered 3/5 of the total distance on foot.

3. Calculate the Time Needed to Cover the Remaining Distance on Bicycle: - Once we have the remaining distance, we can calculate the time needed to cover it at a speed of 12 km/h on a bicycle.

Let's proceed with the calculations.

Calculation Steps

1. Calculate the Total Distance and Distance Covered on Foot: - Total Distance (AB) = 180 km - Distance Covered on Foot = 3/5 * 180 km = 108 km

2. Calculate the Remaining Distance: - Remaining Distance = Total Distance - Distance Covered on Foot - Remaining Distance = 180 km - 108 km = 72 km

3. Calculate the Time Needed to Cover the Remaining Distance on Bicycle: - Time = Distance / Speed - Time = 72 km / 12 km/h = 6 hours

Answer

The tourist will need 6 hours to cover the second distance segment on the bicycle at a speed of 12 km/h.

This calculation assumes a constant speed and no breaks during the journey.
