Every few years, different countries compete in a sailboat race called the America's Cup. The boats sail over the same distance. Besides distance, what else is needed to find out the speed of each boat in the race? (1 point)

Question

The wind speed during the race.
The time it takes for each boat to finish the race.
The combined size of the boats in the race.
The skill of the crew of each boat in the race.

Answer 1

To find out the speed of each boat in the race, you need the time it takes for each boat to finish the race. Speed is calculated using the formula:

\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

Therefore, knowing the wind speed, the size of the boats, or the skill of the crew is not necessary for calculating speed, but time is essential.
