Answer 1

I can help you with this question. The answer is d) 1000 meters. Here is how you can solve it:

- Since the trains are moving in opposite directions, their relative speed is the sum of their individual speeds. So, the relative speed of the trains is 25 + 15 = 40 meters per second. - The time taken for the passenger train to pass the freight train is 25 seconds. This means that the distance covered by the passenger train in this time is equal to the length of the freight train. So, we can use the formula: distance = speed x time. - The distance covered by the passenger train is 25 x 40 = 1000 meters. This is the length of the freight train.
