If a man can cover 18 metres in one second, how many kilometres can he cover in 3 hours 45 minutes?\nOptions:\n(A) 243 km\n(B) 162 km\n(C) 1767 km\n(D) 1887 km\n(E) 177 km

(A)
18 m/s = 18 * 18/5 kmph\n3 hours 45 minutes = 3 3/4 hours = 15/4 hours\nDistance = speed * time = 18 * 18/5 * 15/4 km = 243 km.

The final answer: (A)
