Sign in nowLet the speeds of ‘A’ and ‘B’ be ‘x’ km/h and ‘y’ km/h, respectively According to the question, (x + y) = (60/6) = 10 km/h Multiplying throughout by (2), we get (2x + 2y) = 20………. (I) Also, (2x/3) + 2y = 12 Or 2x + 6y = 36……. (II) Subtracting equation (I) from equation (II), we get ‘y’ = 4 km /h putting the value of y in the equation (ii) x = 6km /h
