Answer

Explanation:

Step1: Analizar la gráfica

En la gráfica de posición - tiempo, el punto de intersección de las dos curvas (una para cada corredor) indica que los corredores están en la misma posición en un instante dado.

Step2: Observar el tiempo t = 45 s

A t = 45 s, la curva de la posición del corredor B está por encima de la curva de la posición del corredor A. Esto significa que el corredor B está más lejos en la pista en ese instante.

Answer:

Runner B passed runner A.
