On the coordinate plane the horizontal axis is labeled t (seconds) and the vertical
axis is labeled s (meters). A line and a curve are graphed.
• The line labeled A begins at the origin, goes up and right, and ends at the point
(14, 100).
. The curve labeled B begins at the origin, goes up and right becoming more
steep, passes through the approximate point (9.5, 55) where the curve B is
furthest from the line A, and ends at the point (14, 100).
escribe and compare how the runners run the race.
