To obtain the wind speed at a height of 120m, you can use the formula: wind speed on deck + (wind speed on deck * 20%). Since the wind speed measured on the deck is 25 km/h, the calculation would be 25 + (25*0.2), which equals to 30 km/h. Therefore, the wind speed at a height of 120m is 30km/h and to obtain this value, you would need to add 5km/h to the measurement on the deck. This is because 20% of 25 km/h is equivalent to 5 km/h, giving us the 30km/h at 120m. Remember that wind speed increases with increase in altitude, so the higher the kite sail, the faster the wind speed. You may need to consider this when flying a kite sail at a higher altitude on a ship.
