A man runs round a circular field of radius 50m at the speed of 12km/hr. What is the time taken by the man to take twenty rounds of the field?

  1. 30 min

  2. 32 min.

  3. 34 min.

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Circumference = 2 * pi * r = 2 * 3.14 * 50 = 314 m. Total distance for 20 rounds = 20 * 314 = 6280 m = 6.28 km. Speed = 12 km/hr. Time = 6.28 / 12 hours = 0.5233 hours = 31.4 minutes. 32 minutes is the closest approximation.
