Local trains leave from a station at an interval of 14 minutes at a speed of 36 km/h. A man moving in the same direction along the road meets the trains at an interval of 18 minutes. Find the speed of the man.	Choose the correct option:
A) 8 km/h	B) 7 km/h	C) 6 km/h	D) 5.8 km/h	E) None of these
Let speed of man = S km/h. Then,   36 × 14⁄60 = 18⁄60[36 - S] ⇒ 36 – S = 28 ⇒ S = 8 km/h.   8 km/hnswer 8 km/h
