Answer 2

Problem Analysis

We are given the following information: - The bus is traveling at a speed of 40 km/h. - The car is traveling at a speed of 80 km/h.

We need to find: 1. The time it takes for the car to catch up to the bus. 2. The distance traveled by both the car and the bus when the car catches up to the bus.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's assume that the car catches up to the bus after time 't'. At that time, the distance traveled by the car will be the same as the distance traveled by the bus.

Let's calculate the time it takes for the car to catch up to the bus:

1. The relative speed of the car with respect to the bus is 80 km/h - 40 km/h = 40 km/h. 2. Since the distance traveled by both the car and the bus is the same, we can set up the equation: distance_car = distance_bus. 3. Using the formula time = distance / speed, we can write the equation as: distance_car / speed_car = distance_bus / speed_bus. 4. Substituting the given values, we have: distance_car / 80 = distance_bus / 40. 5. Since the distances are the same, we can simplify the equation to: distance_car / 80 = distance_car / 40. 6. Solving for distance_car, we get: distance_car = (80 * distance_car) / 40. 7. Simplifying further, we find: distance_car = 2 * distance_car. 8. Dividing both sides of the equation by distance_car, we get: 1 = 2. 9. This equation is not possible, which means the car will never catch up to the bus.

Therefore, the car will not catch up to the bus, and the time and distance cannot be determined.

Conclusion

The car will not catch up to the bus, and therefore, the time and distance cannot be determined.
