1.	If a cyclist completes 4 rounds in 16 minutes around a circular track with uniform speed of 6.28 m/s, then the radius of that track is? A)120m B)180mC)210 m D)240m
Answer» - If a cyclist completes 4 ROUNDS in 16 minutes around a circular track with uniform speed of 6.28 m/s, then the radius of that track is ? A) 120m B) 180mC) 210 m D) 240mSolution :- → 4 rounds in = 16 minutes → 1 round in = 16/4 = 4 minutes .now,→ 1 minute = 60 seconds .→ 4 minute = 240 seconds .then,→ Distance COVERED in one round = Circumference of circular track = Time * Speed = 240 * 6.28 = 1507.2 m therefore,→ 2πr = 1507.2→ 2 * 3.14 * r = 1507.2→ 6.28 * r = 1507.2→ r = 240 m (D) (Ans.)
