Answer» LET distance = x m Usual rate = y kmph x/y x/y+3 = 40/60 hr 2y(y+3) = 9x 1 x/y-2 x/y = 40/60 hr y(y-2) = 3x 2 divide 1 & 2 EQUATIONS by SOLVING we get x = 40. Let distance = x m Usual rate = y kmph x/y x/y+3 = 40/60 hr 2y(y+3) = 9x 1 x/y-2 x/y = 40/60 hr y(y-2) = 3x 2 divide 1 & 2 equations by solving we get x = 40. |
