Homework Statement
Suppose that two runners run a 100-meter dash, but the first runner reaches maximum speed more quickly than the second runner. Both runners maintain constant speed once they have reached their maximum speed and cross the finish line at the same time. Which runner has the larger maximum speed? Explain.
Homework Equations
No relevant equations.
The Attempt at a Solution
I understand that the second runner is the one who reaches a larger maximum speed. I just don't know how it relates to a velocity-time graph. The books explains that "if both runners cover the same distance in the same time interval, then their average velocity has to be the same and the area under the curves on a velocity-time graph are the same". Being that Conceptual Physics is the first physics class I have ever taken I can't grasp this concept. Please help me understand.
