In a 200-meter race, A finishes in 22 seconds and B finishes in 25 seconds. By what distance does A beat B?
A. 24 meters
B. 22 meters
C. 26 meters
D. 25 meters
Answer: Option A
Solution (By JKSSB Mock Tests)
Speed of B = 200 / 25 = 8 m/s. Distance covered by B when A crosses the finish line at 22 seconds = 8 * 22 = 176 meters. Winning margin = 200 - 176 = 24 meters.

A man rows a boat 18 km in 4 hours downstream and returns upstream in 12 hours. Find the speed of the stream.
A. 2 km/h
B. 2.5 km/h
C. 1 km/h
D. 1.5 km/h

Correct Answer: Option D


Explanation:
Downstream speed = 18 / 4 = 4.5 km/h. Upstream speed = 18 / 12 = 1.5 km/h. Speed of stream = (4.5 - 1.5) / 2 = 1.5 km/h.

Question #3
A person covers a distance of 12 km in 1 hour 30 minutes. What is his speed in meters per second?
A. 2.00 m/s
B. 2.22 m/s
C. 2.77 m/s
D. 2.50 m/s

Correct Answer: Option B


Explanation:
Time = 1.5 hours. Speed = 12 / 1.5 = 8 km/h. To convert into m/s, multiply by 5/18. Speed = 8 * (5/18) = 40 / 18 = 2.22 m/s.
