Question

Из одного пункта в противоположных направлениях вышли два велосипедиста. Через 3 часа расстояние между ними будет 330 км. С какой скоростью ехал первый велосипедист, если первый ехал со скорость 75 км/ч? Помогите, ПОЖАЛУЙСТАААААААА

Answer 1

1) 330÷3=110(км/ч) - скорость удаления.
2) 110-75=35(км/ч)
Ответ: 35 км/ч скорость | велосипедиста.

Answer 2

Problem Analysis

We have two cyclists who start from the same point and travel in opposite directions. After 3 hours, the distance between them is 330 km. We need to find the speed at which the first cyclist was traveling, given that their speed was 75 km/h.

Solution

Let's assume that the speed of the first cyclist is x km/h. Since the two cyclists are traveling in opposite directions, the distance between them will increase at a rate equal to the sum of their speeds.

After 3 hours, the distance between them is 330 km. Using the formula distance = speed × time, we can write the equation:

75 km/h × 3 hours + x km/h × 3 hours = 330 km

Simplifying the equation:

225 km + 3x km = 330 km

Subtracting 225 km from both sides:

3x km = 105 km

Dividing both sides by 3:

x km = 35 km/h

Therefore, the first cyclist was traveling at a speed of 35 km/h.

Answer

The first cyclist was traveling at a speed of 35 km/h.

Note: The answer is based on the given information and the assumption that the two cyclists are traveling in opposite directions.
