Answer 2

Given Information:

- Distance between points A and B: 260 km - Speed of the bus: x km/h - Speed of the car: y km/h

1. Difference in Speed:

To find the difference in speed between the bus and the car, we need to subtract the speed of the bus from the speed of the car.

Answer: The speed of the bus is y - x km/h slower than the speed of the car.

2. Ratio of Speeds:

To find the ratio of the bus's speed to the car's speed, we need to divide the speed of the bus by the speed of the car.

Answer: The speed of the bus is y / x times slower than the speed of the car.

3. Time for the Bus:

To find the time it will take for the bus to travel from point A to point B, we can use the formula: time = distance / speed.

Answer: The time it will take for the bus to travel from point A to point B is 260 / x hours.

4. Time for the Car:

To find the time it will take for the car to travel from point B to point A, we can use the same formula: time = distance / speed.

Answer: The time it will take for the car to travel from point B to point A is 260 / y hours.

5. Difference in Time:

To find the difference in time between the car and the bus, we need to subtract the time it takes for the bus from the time it takes for the car.

Answer: The car will take (260 / y) - (260 / x) hours less time than the bus to complete the entire journey.

6. Ratio of Time:

To find the ratio of the time it takes for the car to the time it takes for the bus, we need to divide the time it takes for the car by the time it takes for the bus.

Answer: The car will take (260 / y) / (260 / x) times less time than the bus to complete the entire journey.

7. Rate of Approach:

The rate of approach is the sum of the speeds of the bus and the car.

Answer: The rate of approach of the bus and the car is x + y km/h.

8. Time of Meeting:

To find the time it will take for the bus and the car to meet, we can use the formula: time = distance / rate.

Answer: The bus and the car will meet after 260 / (x + y) hours.
