A baseline boat hull can row 10 km/h in still water. If the river current tracks a velocity of 2 km/h, find the exact sector distance covered downstream by the boat hull in 30 minutes flat. MCQ with Answer and Explanation
A baseline boat hull can row 10 km/h in still water. If the river current tracks a velocity of 2 km/h, find the exact sector distance covered downstream by the boat hull in 30 minutes flat.
A. 8 km
B. 7 km
C. 5 km
D. 6 km
Answer: Option D
Solution (By JKSSB Mock Tests)
Downstream speed = 10 + 2 = 12 km/h. Time = 30 minutes = 0.5 hour. Distance covered = Speed * Time = 12 * 0.5 = 6 km.
Two commuter trains 130 meters and 120 meters long are tracking in opposite directions at speeds of 42 km/h and 48 km/h respectively. In what time will they clear each other?
Excluding stoppages, a transit bus maintains an average speed of 75 km/h, and including stoppages its speed is 60 km/h. Find the stoppage time per hour.
