Question

Из двух посёлков Одновременно навстречу друг друга выехали два велосипедиста и встретились через 20 минут. Расстояние между поселками равно 11 км, Скорость первого велосипедиста 15 км ч С какой скоростью ехал второй велосипедист?

Answer 1

Ответ:

18 км/час скорость второго велосипедиста

Пошаговое объяснение:

20 мин = 1/3 часа

Пусть скорость второго велосипедиста = х км/час. Тогда:

(х + 15) км/ч - скорость сближения велосипедистов

Составим уравнение:

1/3*(х + 15) = 11

1/3х + 5 = 11

1/3х = 6

х = 6 : 1/3 = 6 * 3

х = 18 (км/час) скорость второго велосипедиста

Answer 2

18 км/ч
60:20=3; 15:3=5 ; 11-5=6 ; 6*3=18

Answer 3

Problem Analysis

We have two cyclists who start simultaneously from two villages and meet each other after 20 minutes. The distance between the villages is 11 km, and the speed of the first cyclist is 15 km/h. We need to find the speed of the second cyclist.

Solution

To find the speed of the second cyclist, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the second cyclist using this formula.

Calculation

The distance between the villages is given as 11 km, and the time taken to meet is 20 minutes. We need to convert the time to hours by dividing it by 60.

Distance = 11 km

Time = 20 minutes = 20/60 hours = 1/3 hours

Using the formula, we can calculate the speed of the second cyclist:

Speed = Distance / Time

Speed = 11 km / (1/3) hours

Simplifying the expression:

Speed = 11 km * (3/1) hours

Speed = 33 km/h

Therefore, the speed of the second cyclist is 33 km/h.

Answer

The second cyclist was traveling at a speed of 33 km/h.
