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.
Two trains 120 meters and 130 meters long are running in opposite directions at speeds of 45 km/h and 45 km/h respectively. In what time will they cross each other?
