Question #1
Report Error
A thief is spotted by a policeman from a distance of 150 meters. The thief runs at 11 km/h and the policeman chases him at 12 km/h. Find the distance covered by the thief before he is caught.
Correct Answer: Option C
Explanation:
Relative speed = 12 - 11 = 1 km/h. Time to catch the thief = 0.15 km / 1 km/h = 0.15 hours. Distance covered by thief = Speed * Time = 11 km/h * 0.15 hours = 1.65 km = 1650 meters.
Relative speed = 12 - 11 = 1 km/h. Time to catch the thief = 0.15 km / 1 km/h = 0.15 hours. Distance covered by thief = Speed * Time = 11 km/h * 0.15 hours = 1.65 km = 1650 meters.

A car covers a certain distance at an average speed of 50 km/h in 6 hours. At what speed must it travel to cover the same distance in 5 hours?
Correct Answer: Option B
Explanation:
Distance = 50 * 6 = 300 km. New required speed = 300 / 5 = 60 km/h.
Distance = 50 * 6 = 300 km. New required speed = 300 / 5 = 60 km/h.

A person covers a distance of 12 km in 1 hour 30 minutes. What is his speed in meters per second?
Correct Answer: Option D
Explanation:
Time = 1.5 hours. Speed = 12 / 1.5 = 8 km/h. To convert into m/s, multiply by 5/18. Speed = 8 * (5/18) = 40 / 18 = 2.22 m/s.
Time = 1.5 hours. Speed = 12 / 1.5 = 8 km/h. To convert into m/s, multiply by 5/18. Speed = 8 * (5/18) = 40 / 18 = 2.22 m/s.
