The Indian Institute of Spices Research (IISR) in Kozhikode has achieved a significant milestone in the field of agriculture with the development of a black pepper variety named ‘IISR Chandra.’
The speed of the boat in still water is 12 km/hr and the speed of the stream is 9 km/hr. A boat goes 84 km downstream with its usual speed but at the ti...
A boat can cover 120 km in upstream in 6 hours and 180 km in downstream in 3 hours. Find the speed of the stream.
The time taken by a boat to travel 'd' kilometers downstream is 8 hours, while the time taken to travel (d - 60) kilometers upstr...
A takes 3 hours more while swimming upstream than downstream. His speed in still water is 12 km/hr. The speed of stream is 4 km/hr. What is the distance?
The speed of a boat in still water is 16/ 3 km/ h. It was found that the boat takes thrice as much time to row up as it does to row down the same distan...
A man can go on a motorboat with a speed of 18 km/hour in still water to a certain upstream point and return to the starting point in a river that flows...
When a speed of stream is 25% of the speed of boat in still water. If the boat can travel 60 km upstream in 5 hours and 80 km downstream in 4 hours, the...
A boat travels downstream at a speed of 25 km/h and the stream's current adds an additional 3 km/h to its speed. How long will it take for the boat to ...
If the sum of upstream and downstream speed is 20 km/hr and the speed of the current is 5 km/hr. Then find time taken to cover 45 km in downward?
A boat goes 60 km upstream in 4 hours and 50 km downstream in 2 hours, then the speed of the boat in still water is
