A man wins a race of 100 meters over another man by 10 meters or 2 seconds. Find the time taken by the winner to complete the race.
A. 22 seconds
B. 16 seconds
C. 20 seconds
D. 18 seconds
Answer: Option D
Solution (By JKSSB Mock Tests)
The second man covers 10 meters in 2 seconds, so his speed = 10 / 2 = 5 m/s. Total time taken by second man to complete 100m = 100 / 5 = 20 seconds. Since the winner beats him by 2 seconds, winner's time = 20 - 2 = 18 seconds.
