Question

*90 points* Pls help and give full responses pls!! Look at the graph in the pic.

A. Compare the distances relative to Columbus from which the trains begin their trip.
B. Tom claims both trains traveled at the same speed over a certain interval. Sara claims that both trains traveled at different speeds the entire time. Justify which claim is correct.
​Type your answer in the space provided.

Answer 1

A. Train A begins 1800 miles from Columbus while train B begins 1200 miles from Columbus

B. Train A travels at a constant rate because its graph is a linear equation. Train B does not move until 1pm, when it starts moving towards Columbus at the same speed as train A. I know that trains are traveling at the same speed at a certain interval because they have the same slope at that interval. Because the train was moving at the same speed as train A over a certain interval, Tom is correct.
