Question

С одной и той же станции отправились одновременно в противоположных направлениях поезд и автобус.Скорость поезда 65 км_ч .Найди скорость автобуса если через 3 часа расстояние между ними стало 465 км.

Answer 1

1) 65х3=195 (км) прошел поезд
2) 465-195=270 (км) прошел автобус
3) 270:3=90 (км/ч) скорость автобуса

Answer 2

Problem Analysis

We are given that a train and a bus start simultaneously from the same station in opposite directions. The speed of the train is 65 km/h. After 3 hours, the distance between them is 465 km. We need to find the speed of the bus.

Solution

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

After 3 hours, the train would have traveled a distance of 65 km/h * 3 h = 195 km.

The distance covered by the bus in 3 hours can be calculated by subtracting the distance covered by the train from the total distance between them:

Distance covered by the bus = Total distance - Distance covered by the train Distance covered by the bus = 465 km - 195 km = 270 km

Now, we can use the formula: Speed = Distance / Time to find the speed of the bus.

Speed of the bus = Distance covered by the bus / Time taken Speed of the bus = 270 km / 3 h = 90 km/h

Therefore, the speed of the bus is 90 km/h.

Answer

The speed of the bus is 90 km/h.
