Task data: t1 (duration of uniform movement) = 1.2 h; S1 (distance traveled in time t1) = 2.16 km; t2 (considered travel time) = 12 minutes = 0.2 hours.
Since the speed of a given body is constant, then its movement in 12 minutes is determined using the proportion: S1 / t1 = S2 / t2, whence we express: S2 = S1 * t2 / t1.
Calculation: S2 = 2.16 * 0.2 / 1.2 = 0.36 km or 360 m.
Answer: In 12 minutes, the body will cover a distance of 360 m.
