The speed of two runners are in the ratio 3 : 5. If the first runner takes 40 seconds to complete a loop, how much time does the second runner take?
A. 26 seconds
B. 22 seconds
C. 28 seconds
D. 24 seconds
Answer: Option D
Solution (By JKSSB Mock Tests)
Ratio of speeds = 3:5, so ratio of times taken = 5:3. Given 5 parts = 40 seconds => 1 part = 8 seconds. Time taken by the second runner = 3 parts = 3 * 8 = 24 seconds.
A runner tracks a circular field loop course of radius 70 meters. If his speed registers at 20 m/s, find the total loop rounds completed by him in 2 minutes 12 seconds.
