Answer:
0.4850 knots.
Explanation:
To convert the speed of the California Current from centimeters per second to knots, we can use the conversion factor of 1 knot = 0.514444444 cm/s.
So, 0.25 cm/s * 1 knot / 0.514444444 cm/s = 0.4850 knots.
Therefore, the California Current moves at a speed of approximately 0.4850 knots.
