Soil texture, which includes the proportions of sand, silt, and clay, significantly affects the rate of evaporation from soil. Coarser soils (e.g., sandy soil) tend to have higher evaporation rates.
Two boats X and Y start towards each other from two places, 119 km apart. Speed of the boat X and Y in still water are 7 km/hr and 10 km/hr respectively...
When travelling downstream, a boat takes 6.25 hours to travel 225 km. If the speed of the stream is (1/3)rd of downstream speed of the boat, ...
