Calculation of Meeting Time for Cars

To calculate the time at which the two cars will meet, we need to consider their respective speeds and the time it takes for each car to travel the distance between the two cities.

Let's assume that the distance between the two cities is D.

The speed of the first car (the passenger car) is V1, and it takes this car T1 hours to travel the distance D.

The speed of the second car (the cargo car) is V2, and it takes this car T2 hours to travel the distance D.

To find the meeting time, we can set up the following equation:

T1 = T2

Solving this equation will give us the time at which the two cars will meet.

Calculation Steps

1. From the given information, we know that the passenger car takes 2 hours to travel the distance between the two cities, and the cargo car takes 4 hours to travel the same distance. 2. Let's assign the following variables: - V1: Speed of the passenger car - T1: Time taken by the passenger car to travel the distance - V2: Speed of the cargo car - T2: Time taken by the cargo car to travel the distance 3. We can set up the equation as follows: - T1 = T2 - Since we know that T1 = 2 and T2 = 4, we can substitute these values into the equation: - 2 = 4 4. Since the equation is not true, it means that the two cars will not meet at the same time if they start simultaneously from the two cities.

Based on the given information, the two cars will not meet if they start simultaneously from the two cities.
