Question

С одной и той же станции отправились одновременно в противоположных направленияз поезд и автобус. скорость поезда была 65 км/ч. найди скорость автобуса, если через 3 часа расстояние между ними стало 465 км.

Answer 1

1)65×3=195(км)-проехал поезд.
2)465-195=270(км)-проехал автобус.
3)270÷3=90(км/ч)-скорость автобуса.
Ответ:90 км/ч скорость автобуса.

Answer 2

Чтобы найти скорость нужно расстояние разделить на время. V = S: t . 455:3=155км.в час

Answer 3

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 = 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 = 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.
