A cylist takes 5ounds of a circular track of diameter 196n in 25 minutes .find his speed |
|
Answer» Diameter of the circle = 196 m So, radius of the circle = 196/2 = 98 m Distance TRAVELED by the cyclist = 5 x circumference of the circle (SINCE he traveled 5 rounds). Distance traveled by the cyclist = 5 (2πr) = 5 * 2 * 22/7 * 98 = 3080 m Time taken by him = 25 min = 25*60 = 1500 s Speed of the cyclist = Distance/time = 3080/1500 = 2.05333 m/s The speed of the cyclist = 2.0533 m/s Hope this helps you. |
