    Answer: (1) 55 km/h
    Explanation:-
    Let be the average speed of Menon = X km/h
    Total distance = 600 km
    The average speed of Joshua = 65 km/ h
    Formula – 
    Average speed = Total distance / total speed
    According to the question,
    600/(65 + X) = 5
    600 = 325 + 5X
    5X = 600 – 325
    5X = 275
    X = 275/5
    X = 55 km/h
    Hence, the answer is (1) 55 km/h.
