Answer:
Marcela tardó 6 horas y Roberto tardó 8 horas.
Step-by-step explanation:
Dado que Marcela tardó dos horas menos que Roberto en recorrer una distancia en bicicleta, y sabiendo que el producto de los dos tiempos es de 48 horas, para determinar cuánto tardó cada uno se debe realizar el siguiente cálculo:

X x (X + 2) = 48
8 x 6 = 48
Por lo tanto, Marcela tardó 6 horas y Roberto tardó 8 horas.
