The correct answers are:
- The time it takes for each boat to finish the race.
- The wind speed during the race.
To find out the speed of each boat in the America's Cup race, besides the distance, you need to consider two factors: the time it takes for each boat to finish the race and the wind speed during the race.
First, you would need to measure the time it takes for each boat to complete the race. This can be done using various methods such as timing devices, GPS tracking, or video footage analysis. By recording the start and finish times for each boat, you can calculate the difference to determine the duration of the race for each boat.
Next, you would need to take into account the wind speed during the race. The speed at which the boats sail is greatly influenced by the wind. A stronger wind would generally result in higher boat speeds, while a weaker wind might slow them down. Accurate measurements of wind speed can be obtained using anemometers or by consulting weather reports.
Combining the time it takes for each boat to finish the race with the wind speed during the race will allow you to calculate the speed of each boat. By dividing the distance of the race by the time taken and adjusting for the wind speed, you can determine the speed of each boat in the America's Cup race.
