Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 3:24 p.m.
Concept used:
Relative speed when two objects are going in the same direction = x - y
Calculations:
Distance travelled by the thief in half an hour = 48 × 0.5 = 24 km
Relative speed = 58 - 48 = 10 km/h
Time taken = 24/10 = 2.4 hour or 2 hour 24 minutes
Hence, thief will be caught at = 1 pm + 2 hour 24 min = 3 : 24 pm
