Question

8.f.5
determine which of the following distance vs. time graphs match the situations given. type in the correct letter of each graph next to the description it matches.
a. distance-time graph with two segments of constant distance (stops) and two segments of increasing distance

b. distance-time graph with three segments of constant distance (stops) and three segments of increasing distance

c. distance-time graph with a peak (returning home), a segment of constant distance (at home), and a final segment of increasing distance to school

? 1. kailey got on the bus at her house. the bus made two more stops before it arrived at the school.

? 2. brennan and his dad left for school in his dad’s car. they got stopped at the train tracks for several minutes before they were able to continue to school.

? 3. cameron left for school with his mom but remembered he left his english project at home. she took him back home to get his project, and then they head back to school without any stops.

Explanation:

Step1: Analyze Situation 1

Kailey's bus makes two more stops (total 3 stops: house + 2). Graph B has two plateaus (stops) before final increase, matching 3 segments (start, stop1, stop2, school). So Situation 1 → B.

Step2: Analyze Situation 2

Brennan's car stops at tracks (one plateau) then continues. Graph A has one plateau (flat part) then increase, matching. So Situation 2 → A.

Step3: Analyze Situation 3

Cameron goes to school, returns home (distance decreases), then goes back (distance increases). Graph C has a decrease (return) and then increase, matching. So Situation 3 → C.

Answer:

1. B
2. A
3. C
