The graph shows a bicycle rider's motion during the first portion of a race. What conclusion can be drawn about the rider's motion? A. The rider maintained a constant speed during the time period between 0 and 10 seconds. B. The rider did not move during the time period between 10 and 15 seconds. C. The rider rode downhill during the time period between 15 and 20 seconds. D. The rider slowed down during the time period between 15 and 20 seconds.

Question

from 0 to 10 it is indeed constant. Going up in a straight line.

But between intervals of 10 to 15 it's just a straight line(Horizontal)

between 15 and 20 it shows the line go down.

Answer 1

Based on your description of the graph:

A. The rider maintained a constant speed during the time period between 0 and 10 seconds.

• This is true if the line is a straight diagonal line going upwards, indicating constant speed.

B. The rider did not move during the time period between 10 and 15 seconds.

• This is true if the line is horizontal during this time, indicating that the rider's position did not change.

C. The rider rode downhill during the time period between 15 and 20 seconds.

• This is true if the line slopes downwards during this time, indicating a decrease in position or elevation.

D. The rider slowed down during the time period between 15 and 20 seconds.

• This is likely false unless the slope from 15 to 20 seconds is less steep than the slope from 0 to 10 seconds, which would indicate the rider is still moving but at a slower speed.

Based on this analysis, the correct conclusions are:

• A and B are definitely correct.
• C is also correct.
• D cannot be confirmed without knowing the steepness of the lines.

If the question asks for a conclusion that can be definitively drawn about the rider's motion based on the graph, then options A, B, and C are valid conclusions.

It is not multiple choice. only one answer can be selected

Answer 3

Given that only one conclusion can be selected based on your description of the graph, the best choice would be:

B. The rider did not move during the time period between 10 and 15 seconds.

This is a clear statement based on the horizontal line you've described, indicating that the position did not change during that period. While A and C are also valid observations, B directly indicates a moment of no movement, which is a definitive conclusion based on the information provided.
