Question

two runners jogged around a 400 - meter track. the graph below shows the distance each runner traveled over time. distance vs. time: runners on a track. based on the graph, which statement best describes the motion of the runners? runner b stopped running halfway through the race. runner a ran at a faster constant speed than runner b. runner b ran at twice the speed of runner a. runner a and runner b ran at the same speed.

Explanation:

In a distance - time graph, the slope represents speed. Runner A's line has a steeper slope than Runner B's, indicating a higher constant speed. Runner B's line is also a straight line, so Runner B did not stop. The slopes are not in a 2:1 ratio, so Runner B did not run at twice the speed of Runner A.

Answer:

Runner A ran at a faster constant speed than Runner B.
