The body moved evenly for 15 seconds, while it passed 300m.

To find the constant speed with which a given body should have moved, we use the formula: V = S / t.

Variables: S – distance traveled (S = 300 m); t – elapsed time (t = 15 s).

Calculation: V = S / t = 300/15 = 20 m / s.

Answer: The constant speed was 20 m / s.
