Question

Из пункта А вышел поезд,который двигался со скоростью 60 км ч.Когда он прошёл 100 км ,навстречу ему из пункта В вышел другой поезд ,который двигался со скоростью 50 км ч.Через3 ч поезда встретились .Каково расстояние между пунктами А и В ?

Answer 1

60*3=180(км)-прошёл 1 поезд за 3 часа
50*3=150(км)-прошёл второй поезд за 3 часа
100+180+150=430(км)-между пунктами A и B

Answer 2

Given Information

A train left point A with a speed of 60 km/h. When it had traveled 100 km, another train left point B towards A with a speed of 50 km/h. The two trains met after 3 hours. We need to find the distance between points A and B.

Solution

To solve this problem, we can use the formula: distance = speed × time

Let's calculate the distance between points A and B step by step.

1. Calculate the distance traveled by the first train in 3 hours: - The first train's speed is 60 km/h. - Using the formula distance = speed × time, the distance traveled by the first train in 3 hours is: distance = 60 km/h × 3 h = 180 km 2. Calculate the distance traveled by the second train in 3 hours: - The second train's speed is 50 km/h. - Using the same formula, the distance traveled by the second train in 3 hours is: distance = 50 km/h × 3 h = 150 km 3. Calculate the total distance between points A and B: - When the two trains meet, the sum of the distances traveled by both trains is equal to the total distance between points A and B. - Therefore, the total distance between points A and B is: 180 km + 150 km = 330 km

Answer

The distance between points A and B is 330 kilometers.
