Problem Analysis

We are given that a train traveled a distance of 240 km with a speed of 60 km/h, and an automobile traveled a distance of 400 km. We need to find the speed of the automobile.

Solution

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

Speed = Distance / Time

We know the distance traveled by the automobile is 400 km. To find the time taken by both the train and the automobile, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken by the train and the automobile.

Calculation

The time taken by the train can be calculated as follows:

Time taken by train = Distance / Speed = 240 km / 60 km/h = 4 hours

The time taken by the automobile can be calculated as follows:

Time taken by automobile = Distance / Speed = 400 km / Time taken by train = 400 km / 4 hours = 100 km/h

Therefore, the speed of the automobile is 100 km/h.

Answer

The speed of the automobile is 100 km/h.
