A boat goes 12km upstream and 40km downstream in 8 hours. It can go 16km upstream and 32 km downstream in the same time. Find the equation and speed of boat in still water and speed of the stream. *A)12/x+y + 40/ x-y = 8; 16/x+y + 32/x-y =8 ; 2km/hr , 6km/hrB)12/x + 40/y =8; 16/x + 32/y =8 ; 4km/hr , 8km/hrD)12/x-y + 40/ x+y =8 ; 16/x-y + 32 / x+y =8 ; 6km/hr , 2km/hrC)12/x-y +40/x+y =8 ; 16/x-y + 32/x+y = 10 ; 8km/hr , 4km/hr |
