What defines the block-like soil structure?
Block-like structure occurs when soil particles cling together in nearly square or angular blocks with more or less sharp edges. It is commonly found in the B-horizon where clay has accumulated.
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...
A man can row the boat x km downstream and the same distance upstream in 12 hours. Also, he can row the boat 5x km downstream in 10 hours. At what tim...
The speed of the boat in still water is 10 km/hr and the speed of the stream is 5 km/hr. A boat goes 75 km downstream with its usual speed but at the ti...
A boat covers 45 km downstream in 2 h and the same distance upstream in 10 h. Find the speed (in km/h) of the boat in still water.
If a man rows at the rate of 25 kmph in still water and his rate against the current is 5.5 kmph, then the manrsquo;s rate along the current is...
