Question

С вокзала в 10 часов вышли одновременно два поезда в противоположных направлениях в 13часов расстояние между ними было 330 км первый поезд шел со скоростью 50 км/ ч С какой скоростью шел второй поезд

Answer 1

1)13-10=3(часа) - шли поезда
2)330:3=110(км/ч) - скорость удаления друг от друга
3)110-50=60(км/ч)
Ответ: 60км/ч

Answer 2

Calculation of the Second Train's Speed

To determine the speed of the second train, we can use the formula:

Speed = Distance / Time

Given that the two trains started at the same time and the distance between them was 330 km after 3 hours, we can calculate the speed of the second train.

Let's denote the speed of the first train as v1 and the speed of the second train as v2.

The distance traveled by the first train in 3 hours is 3 * v1.

The distance traveled by the second train in 3 hours is 3 * v2.

Since the total distance between the two trains is 330 km, we can write the equation:

3 * v1 + 3 * v2 = 330

Simplifying the equation, we get:

v1 + v2 = 110

Since the speed of the first train is given as 50 km/h, we can substitute v1 = 50 into the equation:

50 + v2 = 110

Solving for v2, we find:

v2 = 60 km/h

Therefore, the second train was traveling at a speed of 60 km/h.
