A person runs at 8 km/h instead of 6 km/h and consequently covers 10 km more in the same timeframe. Find the baseline distance covered at his normal speed.
A. 25 km
B. 40 km
C. 35 km
D. 30 km
Answer: Option D
Solution (By JKSSB Mock Tests)
Let duration be t hours. Distance difference = 8t - 6t = 2t = 10 km => t = 5 hours. Distance handled at normal speed (6 km/h) = 6 * 5 = 30 km.
A swimmer registers a pace track of 15 km downstream in 3 hours and handles 9 km upstream back in 3 hours. Find the net tracking speed of the current flow.
