Answer 2

Problem Analysis

We are given that two vehicles, an automobile and a motorcycle, start simultaneously from points A and B, which are 672 km apart. The automobile has a speed of 93 km/h, and the motorcycle has a speed of 75 km/h. We need to find out how long it will take for the automobile and the motorcycle to meet.

Calculation

To find the time it takes for the automobile and the motorcycle to meet, we can use the formula:

Time = Distance / Speed

Let's calculate the time for both the automobile and the motorcycle separately.

For the automobile: - Distance = 672 km - Speed = 93 km/h

Time taken by the automobile = 672 km / 93 km/h

For the motorcycle: - Distance = 672 km - Speed = 75 km/h

Time taken by the motorcycle = 672 km / 75 km/h

To find the total time taken for them to meet, we can add the individual times together.

Total time taken = Time taken by the automobile + Time taken by the motorcycle

Let's calculate the total time.

Calculation Results

Using the given values, we can calculate the time it takes for the automobile and the motorcycle to meet.

For the automobile: - Time taken by the automobile = 672 km / 93 km/h = 7.226 hours

For the motorcycle: - Time taken by the motorcycle = 672 km / 75 km/h = 8.96 hours

Therefore, the total time taken for the automobile and the motorcycle to meet is:

Total time taken = 7.226 hours + 8.96 hours = 16.186 hours

Answer

After the start of their journey, the automobile and the motorcycle can meet approximately 16.186 hours later.

Note: The above calculation assumes that the automobile and the motorcycle maintain a constant speed throughout their journey and that there are no other factors affecting their travel time.
