Question

Путешественник за 2 дня прошёл весь путь в первый день он шёл 7 часов и прошёл на 15 км больше чем во второй день когда он шёл только 4 часа какова скорость путешесвенника если она была одинаковой всё время какой путь прошёл путешественник за 2 дня

Answer 1

Рас он шел все время с одинаковой скоростью => 7-4=3 (часа) - он прошел 15 км. Тогда узнаем его скорость: 15:3=5 км/ч. Тогда весь путь он прошел за 5х(7+4)=55 км.

Answer 2

Calculation of the Traveler's Speed

To calculate the traveler's speed, we need to determine the distance traveled and the time taken on each day.

On the first day, the traveler walked for 7 hours and covered a distance that was 15 km more than the distance covered on the second day, when the traveler walked for 4 hours.

Let's assume the distance covered on the second day is x km. Therefore, the distance covered on the first day would be x + 15 km.

To find the traveler's speed, we can use the formula:

Speed = Distance / Time

On the first day: - Distance = x + 15 km - Time = 7 hours

On the second day: - Distance = x km - Time = 4 hours

Now, let's calculate the traveler's speed using the given information.

On the first day, the traveler's speed would be:

Speed = (x + 15) km / 7 hours

On the second day, the traveler's speed would be:

Speed = x km / 4 hours

Since the traveler's speed is the same throughout the journey, we can equate the two speeds:

(x + 15) / 7 = x / 4

To solve this equation, we can cross-multiply:

4(x + 15) = 7x

Simplifying the equation:

4x + 60 = 7x

60 = 7x - 4x

60 = 3x

x = 20

Therefore, the distance covered on the second day (x) is 20 km.

To find the distance covered on the first day, we can substitute the value of x into the equation:

Distance on the first day = x + 15 = 20 + 15 = 35 km

So, the traveler covered a distance of 35 km on the first day and 20 km on the second day.

Now, let's calculate the traveler's speed using the distance and time for either day:

Speed = Distance / Time

On the first day: Speed = 35 km / 7 hours = 5 km/h

On the second day: Speed = 20 km / 4 hours = 5 km/h

Therefore, the traveler's speed is 5 km/h throughout the journey.

Calculation of the Total Distance Traveled

To calculate the total distance traveled by the traveler in 2 days, we can simply add the distances covered on each day:

Total Distance = Distance on the first day + Distance on the second day

Total Distance = 35 km + 20 km = 55 km

Therefore, the traveler covered a total distance of 55 km in 2 days.
