In a covering a certain distance the speed of A and B are in the ratio of 6: 9, A takes 20 min more, than B to reach the destination. The time taken by A to reach the destination is:  Choose the correct option:
A) 1 Hour	B) 2 Hours	C) 1.5 Hours	D) 2.5 Hours	E) 3 Hours
Let the speed of 1 Hour and B are 6x Kmph   and 9x Kmph respectively,   Let the total distance to travel = y Km   y/6x - y/9x = 1/3   y/x(1/18 = 1/3   y = 6x   Required time = 6x/6x = 1 hour   1 Hournswer 1 Hour.6 /6=
