a steamer moving in a river takes m seconds to go 'a' meters downstream and n seconds to go 'a' meters upstream.Find the speed of the river water and the speed of the steamer relative to the river water in m/sec. a steamer moving in a river takes m seconds to go 'a' meters downstream and n seconds to go 'a' meters upstream.Find the speed of the river water and the speed of the steamer relative to the river water in m/sec.
vm + um = a or m(v+u) = avn – un = a or n(v-u) = av = speed of steameru = speed of riverspeed of steamer relative to water will be v – u = vrform above 2 equationsm(vr + 2u) = an vr = afrom these 2 u can calculate u and vr
