LCA Tejas was designed and developed by India's HAL (Hindustan Aeronautics Limited).
The speed of a boat in still water is 45 km/hr, and the speed of the stream is 5 km/hr. The boat takes 30 minutes longer to cover a distance of x km ups...
A boat running downstream covers a distance of 32 km in 4 hrs and covering the same distance upstream in 16 hrs. What is the speed of a boat in still wa...
The speed of the stream is 12 km/h. Boat ‘A’ covers 160 km distance against the stream in 8 hours and boat ‘B’ covers 84 km distance against the...
Speed of a boat in still water to speed of boat in upstream is 11:7. If the boat can travel 300 km in downstream in 5 hours, then find the time taken by...
A man can row his boat with the stream at 14 km/h and against the stream in 8 km/hours. Find the rate of the stream.
The speed of a boat in still water is to the speed of the stream in the ratio 9:4, respectively. The total time taken by the boat to cover a distance of...
If the sum of upstream and downstream speed is 24 km/hr and the speed of the current is 5 km/hr. Then find time taken to cover 51 km in downward?
A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 5 hour to row to a place and come back, how far is the place?
A boat travels faster than the stream by 28 km/h. It covers a distance of 112 km upstream and returns 132 km downstream, all within 7 hours. Calculate t...
A man can row upstream at 18 km/hr and downstream at 24 km/hr. Find the man’s rate in still water and the rate of the current.
