The train, moving evenly at a speed of 150 km / h, passes by the post in 6 seconds. Find the length of the train in meters.

To solve this problem, recall the formula for calculating the distance. Distance is equal to the product of time and speed. s = v * t, where s is distance, v is speed, t is time. Let’s convert seconds to hours. 6 seconds = 6/3600 = 1/600 hours.
Let’s calculate the length of the train.
s = 1/600 * 150 = 150/600 = 0.25 kilometers.
Let’s convert kilometers to meters.
1 kilometer = 1000 meters.
0.25 * 1000 = 250 meters.
Answer: 250 meters.
