Question

2 the graph shows the motion of an object. which letters show the object traveling 5 km in 15 minutes?
select two correct answers.
a line segment ab
b line segment bc
c incomplete option

Explanation:

Step1: Analyze segment AB

Time change: $5-0=5$ minutes, Distance change: $5-0=5$ km. Does not match 15 minutes.

Step2: Analyze segment BC

Time change: $15-5=10$ minutes, Distance change: $5-5=0$ km. Does not match.

Step3: Analyze segment CD

Time change: $30-15=15$ minutes, Distance change: $10-5=5$ km. Matches the requirement.

Step4: Analyze segment EF

Time change: $50-35=15$ minutes, Distance change: $13-8=5$ km (reading from graph: E is at 8 km, F is at 13 km). Matches the requirement.

(Note: The visible options are cut off, but based on the graph, the two correct segments are CD and EF. Assuming option C is Line segment CD, and a later option (e.g., E) is Line segment EF)

Answer:

C. Line segment CD
E. Line segment EF
