Question 1 A policeman starts chasing a thief 30 minutes after the thief had run from a spot. With an average speed of 20km per hour, he takes 2 hours to catch the thief. What is the average speed of the thief? a)16km/hr b)25km/hr c)24km/hr d)18km/hr Answer : a)16km/hr Solution: As given, the average speed of the policeman = 20km/hr. He takes 2 hours to catch the thief, so from formula, "distance = speed x time" we have The total distance covered by the police to catch the thief = 20 x 2 = 40 km (This value is also equal to the distance run by thief before being caught by Police.) Policeman had started late by 30 minutes and took 2 hours to catch the running thief. Above means that the thief takes (30minutes + 2 hours =) 5/2 hours to reach 40km. So the speed of the thief = 40/(5/2) = 40 x 2 / 5 = 16 km/hr. Hence the answer is 16km/hr. Question 2 From a particular spot, Tom started to chase Jerry which had left the spot before 30 minutes. Tom ran acro...
