| **The cart, moving on the table, dripped 15 drops with an interval of 20 cm, every 4 seconds, one drop, what is the speed of the cart.**

To find the speed of movement of a given trolley, we apply the formula: V = L / t.

Values of variables: L – interval between drops (L = 20 cm = 0.2 m); t is the time difference between the appearance of drops (t = 4 s).

Let’s perform the calculation: V = L / t = 0.2 / 4 = 0.05 m / s.

Answer: The given trolley must move at a speed of 0.05 m / s.
