The burned vegetation provides nutrients to the soil, creating a fertile area for planting crops. The cultivated area is used for a few years until the soil fertility declines, after which the land is left fallow and allowed to regenerate through natural processes.
A boat goes 45 km upstream in 6 hours and 60 km downstream in 4 hours. If the speed of the current is doubled, how much time will the boat take to trave...
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 ...
The speed of a boat downstream is 20% more than the speed of the boat in still water. If the boat can travel a distance of 288 km upstream in 18 hours, ...
A boat takes 270 minutes to travel 90 km in upstream. The same boat in the same stream takes 120 minutes to travel 50 km in downstream. Find the distanc...
Speed of a boat in still water is 15 kmph and speed of stream is 12 kmph. A man rows to a place at a distance of 81 km and come back to starting point. ...
