v = 90 km / h = 25 m / s – speed of uniform movement of the train;
t = 2 minutes = 120 seconds – time span.
It is required to determine S (meters) – the distance traveled by the train during the time interval t.
S = v * t = 25 * 120 = 3000 meters = 3 kilometers.
Answer: the train covered a distance of 3 kilometers in 2 minutes.
