Question

2. Два велосипедиста ехали навстречу друг другу. Первый велосипедист проехал 54 км со скоростью 9 км/ч., а второй велосипедист проехал до встречи 48 км. С какой скоростью ехал второй велосипедист?​

Answer 1

1) 54 : 9 = 6 (ч) - время движения до встречи;

2) 48 : 6 = 8 (км/ч) - скорость второго велосипедиста.

Ответ: 8 км/ч.

Answer 2

Відповідь:

1) 56:9=6(ч)

2) 48:6=8(км/ч)

Problem Analysis

Two cyclists are traveling towards each other. The first cyclist travels a distance of 54 km with a speed of 9 km/h, while the second cyclist travels a distance of 48 km. We need to determine the speed at which the second cyclist is traveling.

Solution

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

Speed = Distance / Time

We know the distance traveled by the second cyclist is 48 km. We need to find the time taken by the second cyclist to cover this distance.

To find the time, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken by the second cyclist to cover the distance of 48 km.

Calculation

The distance traveled by the second cyclist is 48 km.

Time = Distance / Speed

Time = 48 km / Speed

Now, we can substitute the value of time into the equation for the first cyclist:

54 km / 9 km/h = 48 km / Speed

To find the speed of the second cyclist, we can cross-multiply and solve for Speed:

54 km * Speed = 48 km * 9 km/h

Speed = (48 km * 9 km/h) / 54 km

Simplifying the equation:

Speed = 8 km/h

Therefore, the second cyclist is traveling at a speed of 8 km/h.

Answer

The second cyclist is traveling at a speed of 8 km/h.
