Question

Турист проехал на велосипеде 80% пути,а остальной путь он прошел пешком и потратил на путь пешком вдвое больше времени, чем на велосипедную езду. Во сколько раз турист ехал на велосипеде быстрее, чем шел?Что больше: 3/8 собранного урожая или 60% этого же урожая?

Answer 1

Расстояние, пройденное на велосипеде 0,8;  пешком- 0,2
время велосипеда t1=0,8/V1. Время пешком t2=0,2/V2
Так как время пешком больше в два раза, то 2*0,8/V1=0,2/V2
V1=8V2

Answer 2

Problem Analysis

A tourist traveled 80% of the distance on a bicycle and the remaining distance on foot. The time taken to walk the remaining distance was twice the time taken to ride the bicycle. We need to determine how many times faster the tourist traveled on the bicycle compared to walking.

Solution

Let's assume that the total distance traveled by the tourist is D units.

The distance traveled on the bicycle is 80% of the total distance, which is 0.8D units.

The remaining distance traveled on foot is 20% of the total distance, which is 0.2D units.

The time taken to walk the remaining distance is twice the time taken to ride the bicycle.

Let's assume the time taken to ride the bicycle is T units.

Therefore, the time taken to walk is 2T units.

To find the ratio of the time taken to ride the bicycle to the time taken to walk, we can divide the time taken to ride by the time taken to walk:

Ratio = T / (2T) = 1/2

Therefore, the tourist traveled on the bicycle 2 times faster than walking.

Answer

The tourist traveled on the bicycle 2 times faster than walking.
