Answer 2

Mathematical Model and Solution

To solve this problem, let's denote the speed of the bus as v km/h. According to the problem statement, the speed of the car is twice the speed of the bus, so the speed of the car is 2v km/h.

We are given that the distance between point A and point B is 50 km. Both the car and the bus arrived at point B simultaneously.

To find the speed of the car, we can use the formula:

Time = Distance / Speed

For the bus, the time taken to travel from point A to point B is:

Time_bus = Distance / Speed_bus = 50 / v

For the car, the time taken to travel from point A to point B is:

Time_car = Distance / Speed_car = 50 / (2v)

Since both the bus and the car arrived at point B simultaneously, their travel times are equal:

Time_bus = Time_car

Substituting the values, we have:

50 / v = 50 / (2v)

To solve for v, we can cross-multiply and simplify the equation:

50 * 2v = 50 * v

100v = 50v

Dividing both sides by 50v, we get:

100 = 50

This equation is not possible, as it leads to a contradiction. Therefore, there is no valid solution for the speed of the car in this scenario.

Please note that the given problem statement may contain errors or inconsistencies, as the equation derived does not have a valid solution. It is always important to double-check the information provided and ensure its accuracy.
