Task data: V (speed of a given boat) = 72 km / h (in SI V = 20 m / s); S (the path traveled by the boat) = 10 km (in SI S = 10 * 10 ^ 3 m).
To determine the time of movement of the boat in question, we use the formula: t = S / V.
Let’s perform the calculation: t = 10 * 10 ^ 3/20 = 500 s (8 min 20 s).
Answer: To travel a path of 10 km, the boat in question will need 8 minutes and 20 seconds.
