Question

Турист должен преодолеть расстояние в 257км.В начале пути он ехал на поезде 3ч со скоростью 67 км /ч. затем шел пешком 4 ч со скоростью 6 км/ч. остальной путь ему нужно преодолеть на велосипеде.сколько км осталось ?

Answer 1

3*67=201км.

4*6=24

257-(201+24)=32км

Answer 2

1) 67*3= 201 КМ- на поезде

2) 6*4=24 КМ - пешком

3) 24+201=225 КМ - на поезде и пешком

4) 257-225=32 КМ

Ответ: 32 КМ

Answer 3

Problem Analysis

A tourist needs to travel a distance of 257 km. Initially, the tourist travels by train for 3 hours at a speed of 67 km/h. Then, the tourist walks for 4 hours at a speed of 6 km/h. The remaining distance is to be covered by bicycle. We need to calculate how many kilometers are left for the tourist to travel.

Solution

To find the remaining distance, we need to calculate the total distance covered by the tourist so far and subtract it from the total distance of 257 km.

Let's calculate the distance covered by the tourist by train: Distance covered by train = Speed of train * Time taken by train

Using the given information: Speed of train = 67 km/h Time taken by train = 3 hours

Distance covered by train = 67 km/h * 3 hours

Next, let's calculate the distance covered by the tourist on foot: Distance covered on foot = Speed of walking * Time taken on foot

Using the given information: Speed of walking = 6 km/h Time taken on foot = 4 hours

Distance covered on foot = 6 km/h * 4 hours

Now, let's calculate the total distance covered by the tourist: Total distance covered = Distance covered by train + Distance covered on foot

Finally, let's calculate the remaining distance: Remaining distance = Total distance - Total distance covered

Calculation

Distance covered by train = 67 km/h * 3 hours = 201 km Distance covered on foot = 6 km/h * 4 hours = 24 km Total distance covered = 201 km + 24 km = 225 km Remaining distance = 257 km - 225 km = 32 km

Answer

The tourist has 32 km left to travel.

Explanation

The tourist initially traveled 201 km by train and then walked an additional 24 km. Therefore, the total distance covered by the tourist is 225 km. Since the total distance is 257 km, the remaining distance is 32 km.
