The correct answer is A
The speed of a boat in still water increases by 4 km/hour after each hour. The speed of stream is 3 km/hour. If the boat travelled 60 km in 3 hours in d...
Speed of a boat in still water is 4 times more than the speed of stream. If boat covers 120 km in downstream in 8 hours, then find the time taken by the...
A boat covers a distance of 108 km downstream in 3 hours. If the ratio of upstream speed to downstream speed of the boat is 5:9, then find the distance ...
A boat can go 15 km upstream and 21 km downstream in 2 hours. If the speed of the stream is 3 km/h, then the time taken (in hours) by the boat to go 21 ...
The speed of the boat in still water is ‘y’ % more than the speed of the boat in upstream. The time taken by the boat to cover (2d+50) km distance i...
A boat moving upstream takes 8 hours 48 minutes to cover a distance while it takes 4 hours to return to the starting point, downstream. What is the rati...
The ratio of the speed of boat in upstream to speed of boat in downstream is 7:9. If the boat can cover a total of 49 km upstream and 81 km downstream i...
A boy can swim in water with a speed of 12 km/hr in still water. If the speed of the stream is 6 km/hr, what will be the time taken by the boy to cover ...
Ratio of speed of boat in downstream and speed of stream is 9:5, if speed of current is 10 km/hr, then find distance travelled (in km) upstream in 6 hours.
