Question

Из двух городов, расстояние между которыми 29км, одновременно в противоположных направлениях выехали два автобуса. Через 4 часа расстояние между ними было 441 км . Найди скорость второго автобуса , нсли первый ехал со скоростью 48 км/ ч. Решите пжл

Answer 1

441 - 29 = 412 км. расстояние между 2 автобусами через 4 часа

412 : 4 = 103 км/ч общая скорость двух автобусов

103 - 48 = 55 км/ч скорость второго автобуса

 

Answer 2

Problem Analysis

We have two buses traveling in opposite directions. The distance between them is 29 km, and after 4 hours, the distance between them becomes 441 km. We need to find the speed of the second bus if the first bus is traveling at a speed of 48 km/h.

Solution

Let's assume the speed of the second bus is x km/h.

After 4 hours, the first bus would have traveled a distance of 48 * 4 = 192 km (since speed = distance/time).

The second bus, traveling in the opposite direction, would have traveled a distance of 441 - 192 = 249 km.

Since the total distance between the two buses is 29 km, we can set up the following equation:

192 + 249 = 29 + 4x

Simplifying the equation:

441 = 29 + 4x

Subtracting 29 from both sides:

412 = 4x

Dividing both sides by 4:

x = 103

Therefore, the speed of the second bus is 103 km/h.

Answer

The speed of the second bus is 103 km/h.
