Answer 3

Problem Analysis

We are given that a train and a bus started simultaneously from the same station in opposite directions. The speed of the train is 65 km/h. After 3 hours, the distance between them became 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 has traveled a distance of 65 km/h * 3 h = 195 km.

The distance covered by the bus in 3 hours is the total distance between them minus the distance covered by the train: Distance covered by the bus = 465 km - 195 km = 270 km.

We can now set up the equation: Distance = Speed * Time

For the bus, the equation becomes: 270 km = x km/h * 3 h

Simplifying the equation, we have: 270 km = 3x km/h

To find the speed of the bus, we can divide both sides of the equation by 3: 270 km / 3 = 3x km/h / 3

Simplifying further, we get: 90 km = x km/h

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

Answer

The speed of the bus is 90 km/h.
