The body, moving evenly in a straight line, moved 25m in 5 seconds. What distance will it cover in 0.5 hours, moving at such a speed.
Since the given body moved uniformly, to calculate its movement in 0.5 hours, one can apply the equality: S1 / t1 = V (velocity, const) = S2 / t2, from where we express: S2 = S1 * t2 / t1.
Variables: S1 – first movement (S1 = 25 m); t2 is the considered duration of movement (t2 = 0.5 h = 1800 s); t1 – first travel time (t1 = 5 s).
Calculation: S2 = 25 * 1800/5 = 9000 m (9 km).
Answer: In 0.5 hours, a given body must travel a distance of 9 km.
