    Answer: (2) 270 km

    Explanation:- 
    Let the total distance traveled a man be X km.

    According to the question,
    X/2 x 60 + X/2 x 45 = 21/4
    X/120 + X/90 = 21/4
    (3 X + 4 X)/360 = 21/4
     7 X/360 = 21/4
    X/90 = 3
    X = 3 x 90
    X = 270 km

    Then, the total distance traveled by him is 270 km.

    Hence, the answer is (2) 270 km.
