Question

Два поезда вышли одновременно навстречу друг другу из двух городов расстояние между которого 650 км и встретились через 5 часов.чему равна скорость второго поезда если скорость первого равна 62 км/ч?

Answer 1

1) 62 км/ч * 5ч = 310 (км) - прошёл первый поезд
2) 650 - 310 = 340 (км) - прошёл второй поезд
3) 340 км : 5 ч = 68 (км/ч) - скорость второго поезда

Answer 2

Problem Setup

Two trains are traveling towards each other from two cities that are 650 km apart. They meet each other after 5 hours. The speed of the first train is 62 km/h. We need to find the speed of the second train.

Solution

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

Total distance = (Speed of first train + Speed of second train) * Time

Given: - Distance = 650 km - Time = 5 hours - Speed of first train = 62 km/h

Using the formula, we can solve for the speed of the second train:

650 = (62 + Speed of second train) * 5

Calculation

Let's solve for the speed of the second train:

650 = (62 + Speed of second train) * 5 650 = 310 + 5 * Speed of second train 5 * Speed of second train = 650 - 310 5 * Speed of second train = 340 Speed of second train = 340 / 5 Speed of second train = 68 km/h

Answer

The speed of the second train is 68 km/h.
