Question

speed problems
match the graph that best fits the motion from the data table.

time (sec)	distance (m)
5	80
10	60
15	40
20	20

Explanation:

Step1: Analyze the data trend

As time increases from 0 to 20 seconds, the distance decreases from 100m to 20m. This indicates a linear - decreasing relationship between time and distance.

Step2: Match with the graphs

Among the given graphs, the graph with a straight - line sloping downwards as time progresses represents a linear decrease in distance with time.

Answer:

The graph in the bottom - left (the one with a straight line sloping downwards as time increases)
