Speed of the car = 2 m/s Time = 11 minutes = 11 × 60 = 660 seconds Distance traveled = Speed × Time = 2 × 660 = 1320 meters Radius of the circular path = 3 meters So, Circumference of the path = 2πr = 2 × π × 3 ≈ 18.85 meters Number of times the car passed point P = Total distance / Circumference = 1320 / 18.85 ≈ 70.06 ✅ Final Answer: About 70 times.
