Question

Please help me! I believe this would be easy.

The graph below shows Roy's distance from his office (y), in miles, after a certain amount of time (x), in minutes:



Four students described Roy's motion, as shown in the table below:


Student Description

Peter He drives a car at a constant speed for 4 minutes, then stops at a crossing for 6 minutes, and finally drives at a variable speed for the next 2 minutes.
Shane He drives a car at a constant speed for 4 minutes, then stops at a crossing for 2 minutes, and finally drives at a variable speed for the next 8 minutes.
Jamie He drives a car at a constant speed for 4 minutes, then stops at a crossing for 6 minutes, and finally drives at a variable speed for the next 8 minutes.
Felix He drives a car at a constant speed for 4 minutes, then stops at a crossing for 2 minutes, and finally drives at a variable speed for the next 2 minutes.


Which student most accurately described Roy's motion?
Peter
Shane
Jamie
Felix

Answer 1

its Felix

Explanation:

i know its correct because i used their answer ^^^^^^

and i got it correct!!

Answer 2

Felix is correct.

Peter and Jaime are wrong for the reason that Roy didn't wait at the cross walk for six minutes, he was stopped there from 4 to 6. Which is two minutes. Shane is wrong because from time 6 to 8 Roy did drive for a variable amount of time but not for a full 8 minutes. He drove for two. Therefore, Felix is right.
Hope I could help!
