Question

Із двох пунктів відстань між якими 26км одночасно на зустріч один одному виїхали два лижники. Один із них рухався зі швидкістю 7.25 км/год а другий із швидкістю на 1.5 більшою. Через який час лижники зустрінутся.(пж дайте розв'язок жду уже 36минут.)

Answer 1

Ответ:

x= 1, 625 год = 97, 5 хв

Пошаговое объяснение:

v2 = 7.25 + 1.5 = 8.75 км/год

Нехай t= x, тоді

7.25x + 8.75x = 26

16x = 26

x= 1, 625 год = 97, 5 хв

Answer 2

To find the time it takes for the two skiers to meet, we can use the formula:

Time = Distance / Relative Speed

Given that the distance between the two points is 26 km and one skier is moving at a speed of 7.25 km/h, while the other skier is moving at a speed 1.5 times greater, we can calculate the relative speed between them.

Let's calculate the relative speed:

Relative Speed = Speed of the first skier + Speed of the second skier

Speed of the second skier = 7.25 km/h * 1.5 = 10.875 km/h

Relative Speed = 7.25 km/h + 10.875 km/h = 18.125 km/h

Now, we can calculate the time it takes for the skiers to meet:

Time = Distance / Relative Speed

Time = 26 km / 18.125 km/h

Time ≈ 1.43 hours

Since 1 hour is equal to 60 minutes, we can convert the decimal part of the time into minutes:

0.43 hours * 60 minutes/hour ≈ 25.8 minutes

Therefore, the two skiers will meet approximately 1 hour and 26 minutes after they start simultaneously from the two points that are 26 km apart.

Please note that the above solution assumes a constant speed for both skiers throughout the entire duration of their travel.
