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.
