Under conservation tillage how much of the field area is covered with the residue of crop?
Under conservation tillage which was started in USA 30-50% of field area is covered with residue of crop.
If the sum of upstream and downstream speed is 48 km/hr and the speed of the current is 4 km/hr. Then find time taken to cover 84 km in downward?
A boat goes 8 km an hour in still water, but takes twice as much time in going the same distance against the current. The speed of the current (in km/ho...
A ship covers a distance of 240 km downstream in a time that is 2 hours shorter than the time it takes to cover the same distance upstream. The ship's u...
If a man rows 8km downstream in 6 hours and 4km upstream in 4 hours, then how long will it take him to cover 14km in still water?
A boat takes 24 hours to cover 'q' km in still water. While traveling downstream, it takes 16 hours to cover (q - 80) km. If the speed of the boat in st...
A man can row at a speed of 64 km/h in still water to a certain upstream point and back to the starting point in a river which flows at 8 km/h. Find his...
The downstream speed of a boat is 8 km/hr more than its upstream speed and the ratio of the speed of the boat in still water to the speed of the stream ...
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...
