Question

Турист шел 3 часа пешком и4 часа на велосипеде всего проделал путь 62 км с какой скоростью шёл пешком если шёл на 5 км в час медленнее чем на велосипеде.

Answer 1

Х(км/ч)- скорость когда шел пешком
х+5(км/ч)- скорость на велосипеде
3х(км)- расстояние прошел пешком
(х+5)*4(км)- расстояние проехал на велосипеде
62 км всего
3х+(х+5)*4=62
3х+4х+20=62
7х=62-20
7х=42
х=42:7
х=6(км/ч)- скорость туриста с которой шел пешком

Answer 2

Ответ : 6 км/ч ответ верный

Answer 3

Calculation of Walking Speed

To calculate the walking speed, we need to determine the distance traveled on foot and the time taken to cover that distance.

Given: - Time spent walking: 3 hours - Time spent cycling: 4 hours - Total distance traveled: 62 km - Walking speed is 5 km/h slower than cycling speed

Let's calculate the distance traveled on foot and the walking speed.

The time spent walking is 3 hours, and the time spent cycling is 4 hours. Therefore, the time spent on both activities is 3 + 4 = 7 hours.

To find the distance traveled on foot, we need to subtract the distance traveled on the bicycle from the total distance. The distance traveled on the bicycle can be calculated by multiplying the cycling speed by the time spent cycling:

Distance traveled on the bicycle = Cycling speed * Time spent cycling

Let's assume the cycling speed is x km/h. Therefore, the distance traveled on the bicycle is x * 4 km.

The total distance traveled is 62 km. Therefore, we can write the equation:

Distance traveled on foot + Distance traveled on the bicycle = Total distance

Distance traveled on foot + x * 4 km = 62 km

Now, we know that the walking speed is 5 km/h slower than the cycling speed. Therefore, the walking speed can be expressed as (x - 5) km/h.

Substituting the walking speed into the equation, we get:

Distance traveled on foot + (x - 5) * 4 km = 62 km

Simplifying the equation, we have:

Distance traveled on foot + 4x - 20 km = 62 km

Rearranging the equation, we get:

Distance traveled on foot = 82 km - 4x

Now, we can substitute the value of the distance traveled on foot into the equation:

82 km - 4x + x * 4 km = 62 km

Simplifying the equation further, we have:

82 km - 4x + 4x = 62 km

The x terms cancel out, leaving us with:

82 km = 62 km

This equation is not possible to solve, as it leads to a contradiction. Therefore, there seems to be an error in the given information or calculation.

Unfortunately, we cannot determine the walking speed with the given information. If you have any additional information or if there was a mistake in the given data, please let me know, and I'll be happy to assist you further.
