Question

A person wins a 100-meter race in 12 seconds, while the runner-up finishes in 13 seconds. By what distance did the winner beat the runner-up?

A. 8.50 meters

B. 8.12 meters

C. 7.69 meters

D. 7.24 meters

Answer: Option C

Solution (By JKSSB Mock Tests)

Speed of runner-up = 100 / 13 m/s. Distance covered by runner-up in 12 seconds = (100 / 13) * 12 = 1200 / 13 = 92.31 meters. Beat distance = 100 - 92.31 = 7.69 meters.

Correct Answer: Option C

Explanation:
Downstream speed = 6 + 2 = 8 km/h. Upstream speed = 6 - 2 = 4 km/h. Let distance be d. d/8 + d/4 = 3 => (d + 2d)/8 = 3 => 3d/8 = 3 => d = 8 km.
