Question

Из двух населенных пунктов одновременно навстречу друг другу выехали два велосипедиста. Они встретились через 3ч. В час один из велосипедистов проходит на 2 км больше другого. Какова скорость каждого велосипедиста, если расстояние между населенными пунктами 66 км? Решение с использоваием систем.

Answer 1

1 решение 1 решение 66 надо умножить на 2 мы получаем 132

Answer 2

66×2=132 всё очень просто

Answer 3

Problem Analysis

Two cyclists start from two different points and ride towards each other. They meet after 3 hours. One cyclist covers 2 km more in an hour than the other. The distance between the two points is 66 km.

Solution

Let's denote the speed of the first cyclist as v km/h and the speed of the second cyclist as v+2 km/h.

The total distance covered by both cyclists in 3 hours is 66 km.

Calculation

Using the formula distance = speed × time, we can set up the following equation: - For the first cyclist: v × 3 - For the second cyclist: (v+2) × 3

Adding these distances together gives us the total distance: 3v + 3(v+2) = 66

Solving for v will give us the speed of the first cyclist. Then, we can find the speed of the second cyclist by adding 2 to the speed of the first cyclist.

Calculation

Let's solve the equation: 3v + 3v + 6 = 66 6v + 6 = 66 6v = 60 v = 10

So, the speed of the first cyclist (v) is 10 km/h. The speed of the second cyclist is 12 km/h.

Therefore, the speed of the first cyclist is 10 km/h and the speed of the second cyclist is 12 km/h.

Final Answer

The speed of the first cyclist is 10 km/h and the speed of the second cyclist is 12 km/h.
