Some question: If a man can cover 10 metres in one second, how many kilometres can he cover in 3 hours 45 minutes?
Options:
(A) 135 km
(B) 125 km
(C) 115 km
(D) 105 km
(E) 235 km
Some stream of consciousness:
10 m/s = 10 * 18/5 kmph
3 hours 45 minutes = 3 3/4 hours = 15/4 hours
Distance = speed * time = 10 * 18/5 * 15/4 km = 135 km. The answer: (A).
