Connecting the physical racetrack directly to graph slopes • The Equal-Time Proof
Read the mission card on the right, then click that exact section directly on the graph canvas!
Hint: Time keeps ticking forward continuously on the horizontal (bottom) line. Look for seconds (s)!
Middle school exams test this exact comparison. Here is the step-by-step visual proof in plain English:
Pick any vertical time point on the bottom X-axis. Let's pick 5 seconds for both objects. Both have had the exact same amount of time to travel!
Look at the Y-axis (Distance):
• Object 1 only reached 25 meters.
• Object 2 climbed all the way to 50 meters!
Because Object 2 covered double the distance in the exact same time, its line had to climb twice as steep!
