Answer 2

Calculating the Length and Speed of the Freight Train

To find the length of the freight train and its speed, we can use the formula:

Length = Speed × Time

Given: - Time taken to pass a tree = 25 seconds - Time taken to pass a bridge of length 600 meters = 55 seconds

Let's calculate the length and speed of the freight train using the given information.

Calculating the Length of the Freight Train

Using the time taken to pass the bridge, we can calculate the speed of the freight train.

Speed = Distance / Time

The speed of the freight train passing the bridge: - Distance = 600 meters - Time = 55 seconds

Speed = 600 / 55 = 10.91 m/s Now, we can use the speed to calculate the length of the freight train when passing the tree.

Length = Speed × Time - Speed = 10.91 m/s - Time = 25 seconds

Length = 10.91 × 25 = 272.75 meters

Results

- The length of the freight train is approximately 272.75 meters. - The speed of the freight train is approximately 10.91 m/s.
