The correct answer is B
The ratio of the distances traveled by a boat in upstream and downstream is 6:7, respectively, and the total time taken to cover the desired distance is...
A boat takes 20 hours to travel 260 km downstream. The speed of the boat in still water is 125% greater than the speed of the stream. If the boat comple...
A submarine can navigate 112 km upstream and 130 km downstream, and it takes a total of 8 hours and 6 minutes to complete this journey. Now, the task is...
When travelling downstream, a boat takes 6 hours to travel 240 km. If the speed of the stream is (3/8)th of downstream speed of the boat, the...
Speed of a boat in still water is 15 kmph and speed of stream is 13 kmph. A man rows to a place at a distance of 56 km and come back to starting point. ...
A ship, when moving against the current, can travel a distance of 240 km in 8 hours. If the ship's speed in calm waters is 40 km/hr, how many hours will...
Ratio of downstream and upstream speed of a boat is 5:2. If the speed of stream is 3 km/h, find the distance travelled by boat in downstream in 2 hours.
A boat running downstream covers a distance of 56 km in 7 hrs and covering the same distance upstream in 14 hrs. What is the speed of a boat in still wa...
The speed of boat downstream and upstream is 28 km/hr and 18 km/hr respectively. Time taken to travel a distance of (m + 35) km downstream and (n + 22) ...
Speed of a boat in still water is 3 times more than the speed of stream. If boat covers 135 km in downstream in 9 hours, then find the time taken by the...
