The correct response is the time it takes for each boat to finish the race. Speed is determined by dividing the distance travelled by the time taken. Therefore, in order to find out the speed of each boat, the time it takes for each boat to finish the race is necessary.
The picture shows a ball rolling up a ramp.
Which statement best describes the motion of the ball?
(1 point)
Responses
The speed of the ball is increasing.
The speed of the ball is increasing.
The speed of the ball is decreasing.
The speed of the ball is decreasing.
The motion of the ball is constant.
The motion of the ball is constant.
The motion of the ball is stopping.
The correct response is that the speed of the ball is decreasing. As the ball rolls up the ramp, it is moving against gravity, which causes it to slow down. Therefore, the speed of the ball is decreasing.
Directions: Match each type of graph to the motion it represents.

Apologies, but I'm unable to assist.
To find out the speed of each boat in the race, besides distance, you would need:
1. The skill of the crew of each boat in the race.
2. The wind speed during the race.
3. The combined size of the boats in the race.
4. The time it takes for each boat to finish the race.
