Within 30 seconds, the train was moving evenly at a speed of 72 km / h, what distance did the train travel during this time ..

Since the train was moving evenly, the distance traveled by it can be calculated using the formula:

S = V * t, where V is the train speed (V = 72 km / h = 72 * 1000/3600 = 20 m / s), t is the train travel time (t = 30 s).

Let’s calculate the distance traveled by the train:

S = V * t = 20 * 30 = 600 m.

Answer: Within 30 seconds, the train will pass 600 m.
