Every few years, sailboats of different countries compete in a race for a trophy called the America's Cup. The boats sail over the same distance. What, besides the distance, is needed to find out the speed of each boat in the race?

Question

a
the skill of the crew of each boat in the race
b
the size of each boat in the race
c
the speed of the wind during the race
d
the time it takes each boat to finish the race

Answer 1

To find out the speed of each boat in the race for the America's Cup, you need to know the distance it traveled and the time it takes each boat to finish the race. Therefore, the correct answer is:

d) the time it takes each boat to finish the race.

Using the formula for speed (speed = distance/time), if you know the distance and the time, you can calculate the speed.
