Question
This system of irrigation supplies water to the plant
equivalent to its consumptive use-Solution
Drip irrigation system supplies water drop by drop at the rhizosphere thus exactly compensating the requirement of water by the plant.
A boat moves at 40 km/hr downstream and 10 km/hr upstream. How long will it take to cover 150 km in still water?
The boat's speed in still water is 20% greater than the speed of the stream. If it takes the boat 4 hours more to travel 176 km d...
A boat can travel 270 km downstream in 9 hours and 63 km upstream in 14 hours. Find the speed of the current.
- A boat's speed in still water is 10 km/hr, and the current's speed is 3 km/hr. The boat takes a total of 15 hours to cover ‘x’ km each way (upstream an...
Speed of a boat in still water to speed of boat in upstream is 12:7. If the boat can travel 340 km in downstream in 5 hours, then find the time taken by...
Ratio of speed of boat in downstream and speed of stream is 7:5, if speed of current is 5 km/hr, then find distance travelled (in km) upstream in 4 hours.
Speed of current is equal to 30% of speed of boat in still water. If the boat takes 6 hours to cover 120 km in still water, then find the time taken by ...
A man can row at 6 kmph in still water. If the velocity of current is 3 kmph and it takes him 8 hour to row to a place and come back, how far is the place?
A ship covers 96 km upstream and 144 km downstream in 8 hours and 6 hours, respectively. Find the time taken by the same ship to cover 180 km in still w...
A boat can travel 36 km downstream in 40 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 4. How much time will t...
