In a jeep driving at a speed of 9 m/s, a thief is fleeing on a straight road. He is being pursued by a police officer riding a motorbike at a speed of 10 m/s. How long would it take a police officer to apprehend the burglar if there is a 100 m instantaneous distance between the vehicle and the motorbike?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 100 s.
Speed of thief (jeep) = 9 m/s
Speed of police officer (motorbike) = 10 m/s
Distance between them = 100 m
Since both are moving in the same direction:
Relative speed = 10 m/s – 9 m/s = 1 m/s
Time = Distance / Relative Speed
Time = 100 m / 1 m/s = 100 seconds
