Question

Из двух городов навстречу друг другу одновременно отправились два поезда Скорость одного 60 километров час другой за 1 час проходит на 20 километров больше через 3 часа 30 минут Поезда встретились Найди расстояние между городами

Answer 1

60*3.30часа=210 (1поезд) 80*3.30ч.=280 (2поезд) 210+280=490км между ими было

Answer 2

Calculating the Distance Between the Cities

To calculate the distance between the two cities, we can use the formula: distance = speed * time.

Let's denote the speed of the first train as v1 and the speed of the second train as v2. The time it takes for the trains to meet is denoted as t.

Given: - Speed of the first train, v1 = 60 km/h - Speed of the second train, v2 = 60 + 20 = 80 km/h (as it travels 20 km/h faster than the first train) - Time, t = 3 hours 30 minutes = 3.5 hours

Using the formula distance = speed * time, we can calculate the distance between the cities.

Calculations

The distance traveled by the first train, d1, is given by: d1 = v1 * t = 60 km/h * 3.5 h = 210 km

The distance traveled by the second train, d2, is given by: d2 = v2 * t = 80 km/h * 3.5 h = 280 km

Finding the Total Distance

The total distance between the cities is the sum of the distances traveled by both trains: Total distance = d1 + d2 = 210 km + 280 km = 490 km

So, the distance between the two cities is 490 kilometers.
