Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 500 m .
Relative speed = 11 km/h – 10 km/h = 1 km/h
Convert to m/min: 1 km/h = 1000 / 60 = 16.67 m/min
In 12 minutes, distance increased = 16.67 × 12 = 200 meters
Initial distance = 300 m
After 12 minutes: 300 + 200 = 500 meters
